Reduces the size of the tab buttons on the flag page:
- Sets the min width to 100px instead of 160px on md screens. No change
for smaller screens
- Removes the min-height restriction imposed by theme.ts for the tab
bar, instead relying on the tab buttons to determine the height
(effectively changes the height from 70px to 62px).
Additionally: fixes an issue where the action buttons would overlap with
the tab buttons before wrapping and makes the tab bar scrollable. I can
no longer reproduce the issue where the action buttons force the tab bar
to be too small, but even if they should do that now, the tab bar is
scrollable so the remaining tabs are still accessible.
Because we only override the tabs' min-width on wider screens and mui
sets a default min-width, I changed the `onNarrowHeader` function to
`onWideHeader` and adjusted the other components accordingly. As a
bonus, the tab width and header wrapping now happens at the same time 🥳
After the change:

## Accessibility
This PR also addresses some of the a11y issues with this tab bar, namely
that it adds an `aria-label`, as mentioned in the [MUI
docs](https://v5.mui.com/material-ui/react-tabs/#accessibility).
It does **not**, however, connect the tabs to their corresponding tab
panels. The main reason for this is that we're not using tab panels and
that they're spread over 4 different components. We're probably using
the tabs component for something it isn't really designed to do in this
way. (Arguably they should be links and not buttons, for instance.) I'm
not going to touch this now, because that would probably be a lot of
work and it's not something I expect the business would prioritize.
## Changing theme.ts
While it's tempting to go in and change the `min-height` in `theme.ts`,
that would potentially affect all the other tab bars we have (although
maybe not, because we set a different min height for the tabs
themselves), I want to leave that for now. There is apparently some work
being done/prepared for the tabs, so it's probably better to leave that
for then.
Makes it so that the actions/tabs wrap on narrow width screens.
Constraints:
- When wrapping, the actions should go **before** the tabs, when not
wrapping, they should be placed **after**
- Need to maintain a logical tab order for wrapping, so just using
`flex-flow: row wrap-reverse` doesn't work because the tab order will be
wrong
- When the elements switch, you shouldn't lose your tab place in the
document
This solution uses container queries to determine the container size and
uses that to set the wrapping. Falls back to media queries if container
queries aren't supported (it's supported on >93% of browsers according
to caniuse).
The wrapping points don't use predefined media queries because:
- containers don't care about the size of the screen. It's the intrinsic
size of the container that matters.
- wrapping at 900px seemed too far out if container queries are
unsupported. But it's a fallback, so we can switch to that if we want.
If your keyboard focus is on one of the actions on a wide screen, and
the screen goes narrow, your focus will still be after the tabs (staying
consistent), so tabbing to the next element will take you into the flag
details, while backtab takes you back to the tabs.

## A note on accessibility:
The spec for flexbox (taken from [MDN's
doc](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_flexible_box_layout/Ordering_flex_items))
states:
> "Authors must not use order or the *-reverse values of
[flex-flow](https://developer.mozilla.org/en-US/docs/Web/CSS/flex-flow)/flex-direction
as a substitute for correct source ordering, as that can ruin the
accessibility of the document."
So even if wrap-reverse works visually, it's not a good solution for
this.
- Button to show and hide environments
- Refactored hook storing state of hidden environments
- Changed the way flag is triggered for feature overview
- Visual updates for new page look

This PR moves the flag page header into a separate file, so that the
overview file is more clearly focused on the overview.
Additionally, it moves the modals that are triggered from the header
into the new file. This should give a nice little performance boost, as
opening and closing these modals should no longer trigger a re-rendering
of the full flag overview page, only the header.
If the average number of days in a stage is 1, use `1 day` instead of
`1 days`.
Likewise, if your total number of archived flags is 1, use `1 flag
archived` instead of `1 flags archived`.
I grepped through the file, but couldn't find any other hardcoded
instances of "flags" or "days", so I think this is everything.
Fixes a bug where the dashboard would scroll you down from the top of
the page on load if your window was too short too see both the
selected flag and the selected project.
This solves it by immediately scrolling to the top of the page after
scrolling your selected element into view. Because this hook only runs
on page load, it shouldn't be safe. (At least I couldn't make this
misbehave with manual testing).
It also changes the list scroll behavior to scroll your selected item
to the top of the list instead of to the bottom (effectively). During
testing, that seems like a better solution to me.
## Background (or why do we auto-scroll here?)
The dashboard's flag and projects panels stores your last selection,
so that when you return to the page you'll be shown what you were
looking at last. This is especially useful if you have a lot of flags
but you're focusing on one in particular.
However, if you **do** have a lot of flags, then it's also quite
likely that your selection will be "below the fold" of the panel, and
you won't see your selected flag/project immediately in the
list (without scrolling).
It seemed like a nice UI affordance to automatically bring your
selected item into view (especially because without it, there's no way
to see what flag/project) you're looking at, so I added the
[`scrollIntoView`](https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView)
hook.
What I didn't realize, however, is that it scrolls all scrollable
ancestor containers, which means that if your screen is too short,
it'll scroll you down the page.
From my reading of the docs and some local testing, I don't think
there is a way to limit the scrolling to only the nearest ancestor, so
the easiest way to ensure that we're always at the top seemed to be to
just scroll to the immediately after.
Fixes the height discrepancy between add strategy and more strategies
buttons, both with and without the flag enabled.
The essence of the fix is to make the "more strategies" button's height
dynamic and grow to match the height of the other button.

As a bonus: also enables the ui font redesign flag for server-dev.
If you're very sharp-eyed, you might notice a few things:
1. There's more padding on the new button. This was done in concert with
UX when we noticed there was more padding on other buttons. So as a
result, we set the button type to the default instead of "small".
1. The kebab button isn't perfectly square with the flag on. There's a
few issues here, but essentially: to use `aspect-ratio: 1`, you need
either a height or a width set. Because we want everything here to be
auto-generated (use the button's intrinsic height), I couldn't make it
work. In the end, I think this is close enough. If you have other ideas,
you're very welcome to try and fix it.
Also, use extra css selectors to increase specificity so that this
takes precedence over the MUI themes.
I don't like that we need to do this weird selector thing, but hey, it
is what it is.
Adds the button styles that were removed from `app.css` into the
legacy theme file. These change very slightly when the flag is on, and
because the hardcoded `app.css` styles have been removed, we'll use
the legacy file as fallback.
Fixes a small number of accessibility issues that Firefox was
complaining about (and some that I noticed myself):
1. In `CommandBar.tsx`, use a `Label` element instead of aria-label. We
can hide it with the `ScreenReaderOnly` component.
2. Add an `aria-label` to the icon button in the sidebar. (side note:
should we do any fancy detection on whether it's cmd + b or ctrl+b
there? I think we do that in the command bar)
3. Update the playground guidance popper;
i. Add an aria-label to the icon button
ii. Make the popper a `Popover` instead. This fixes a few issues: It
wasn't possible to focus or close just using the keyboard before.
Because it didn't steal focus, it also meant that it'd cover other parts
of the page. Now it traps focus so you can navigate to the close button,
and escape will also close it for you.
iii. Remove aria-describedby. Using aria-describedby on the button would
mean that the **button** is described by its content, which seems wrong.
aria-describedby should also only be used for plain strings. Complex
markups isn't supported. For that aria-details is the right way to go.
But because the popover is only rendered when it's open, the details or
describedby link will point to nothing most of the time.
iv. In doing this, there is a slight change in the popover shadow (I
couldn't find onef of our shadows that did the same thing as before),
but it matches other popovers we have, such as on the data usage tab.

After:

The license check API call was giving me 404s in the console of the
OSS version of Unleash.
This changes the `useLicense` hook to use `useEnterpriseSWR` instead
of `useSWR` to avoid making the API call in the OSS version. This is
consistent with the `useLicenseCheck` hook in the same file.
Fixes a small visual glitch where the event timeline panel (which
usually doesn't have a bottom border on the summary) would get a
bottom border during the collapsing animation.
This happens because to make the border act as we want, we switch
between using the summary's bottom border and the content's top
border, and I'd only updated one of the borders to respect the new
design.
Extracts each panel into its own component for the personal dashboard.
This lets us use separate states for each panel, which in turn lets each
panel change its open / close state without causing the other panels to
re-render.
When you have a lot of flags and/or projects, the list to render becomes
very long, which causes performance problems, especially when you need
to rerender both flags and projects and the timeline whenever one of
them changes.
The problems were especially noticeable in Firefox for me. Even with
this, the event timeline is a little choppy. I suspect that's because of
it might take a long time to paint? But we can look into that later.
Also updates the dashboard state hook to let you only pass in the
flags/projects you want. We could extract this into three different
hooks that all use the same localhost key, but I'm not sure whether
that's better or worse 🤷🏼
Prevents tab from navigating you through the list of results. Instead
makes it so that the tab key always takes you to the next item in the
same hierarchy.
As a bonus: also automatically closes the menu when you navigate
away (the previous implementation has a bug where it wouldn't if you
shift-tab).
The behavior of not letting you navigate the list with tab is
consistent with native HTML select elements as well as MUI select
elements. You typically navigate them with the arrow keys.
