**Upgrade to React v18 for Unleash v6. Here's why I think it's a good
time to do it:**
- Command Bar project: We've begun work on the command bar project, and
there's a fantastic library we want to use. However, it requires React
v18 support.
- Straightforward Upgrade: I took a look at the upgrade guide
https://react.dev/blog/2022/03/08/react-18-upgrade-guide and it seems
fairly straightforward. In fact, I was able to get React v18 running
with minimal changes in just 10 minutes!
- Dropping IE Support: React v18 no longer supports Internet Explorer
(IE), which is no longer supported by Microsoft as of June 15, 2022.
Upgrading to v18 in v6 would be a good way to align with this change.
TS updates:
* FC children has to be explicit:

* forcing version 18 types in resolutions:
https://sentry.io/answers/type-is-not-assignable-to-type-reactnode/
Test updates:
* fixing SWR issue that we have always had but it manifests more in new
React (https://github.com/vercel/swr/issues/2373)

This fixes the case when a customer have thousands of strategies causing
the react UI to crash. We still consider it incorrect to use that amount
of strategies and this is more a workaround to help the customer out of
a crashing state.
We put it behind a flag called `manyStrategiesPagination` and plan to
only enable it for the customer in trouble.
This PR updates the way we show deleted strategies in the CR UI. Instead
of showing just the strategy name and a diff on hover, we show the same
strategy config as we do for new and updated strategies.
This makes it easier to see what you have deleted.
In doing so, it also fixes two issues:
1. inconsistent border radius for segment changes listed. Due to an
override in `frontend/src/themes/theme.ts`, these would get a border
radius of `theme.shape.borderRadiusLarge` instead of
`theme.shape.borderRadiusMedium`. It does this by adding a class and
making the selector more specific.
2. The background was unset for the strategy rollout box and constraint
item boxes.
It looks like this:

src="https://github.com/Unleash/unleash/assets/17786332/832be653-3def-4afc-b72f-36fcd76ad83d">
Or with more kinds of strategies:
<img width="454" alt="image"
src="https://github.com/Unleash/unleash/assets/17786332/f18e5482-7d2e-4cbd-8177-9de6dfb10307">
Note: I'm happy to isolate the color changes to a separate PR if that's
preferable.
This changes the two interfaces IChangeRequest and
IChangeRequestSchedule to be union types instead of interfaces. It also
extracts the constituents of those union types into proper types
themselves (so that they can be used in function type signatures etc).
It also updates the type names.
This turned out to be more work than I had imagined, but I think the end
result pays off, giving us more type safety and control.
I wanted to use just `ChangeRequest` for the IChangeRequest type, but
that caused issues due to naming collisions with the `ChangeRequest`
component that we have, causing tests to fail. I've named it
`ChangeRequestType` as a potential solution, but suggestions are
welcome.
The relevant changes are in
`frontend/src/component/changeRequest/changeRequest.types.ts`.
Everything else is updated references and some necessary refactoring to
respect the new types.
Show a warning about how deleting a strategy might mess up scheduled
change requests.
If there are change requests, list them. If there are no conflicts, show
nothing. If we don't know (because of no successful response from the
API), say that it might cause issues.

We love all open-source Unleash users. in 2022 we built the [segment
capability](https://docs.getunleash.io/reference/segments) (v4.13) as an
enterprise feature, simplify life for our customers.
Now it is time to contribute it to the world 🌏

environment in turned on
- Adds functionality to either `enable` the strategies or add the
default one (if a project specific default strategy is set, uses it)

## About the changes
Creating the first version of the Dark theme
Refactor: colors variables
Refactor: use theme variable instead
- this change will help us to use MuiCssBaseline, and we can use classes
directly for easy customization when we can't identify MUI classes
Refactor: adjusting some files components
- i’ve touched also the structure of some files, not only the colors
variables (but only to adjust the style, not functionality)
Fix: dark mode persistence on refresh (by Nuno)
Feat: dark mode sees light logos, and light mode sees dark logos (by
Nuno)

## About the changes
Refactoring the colors for the light theme to be much easier to continue
with dark mode
This is the first step to finish dark mode
https://linear.app/unleash/project/[low][s][alpha]-dark-mode-in-unleash-admin-ui-31b407d13c4b/1
This PR uses `main-theme` as a placeholder for `dark-theme` for now due
to the new changes. Still need to set the correct values here.
