https://linear.app/unleash/issue/2-758/add-variant-improve-the-flow
### Variants form
- Fix variants edit form to follow natural tab order;
- Update variants form UI to new design with multiple improvements and
fixes, including a sticky header;
- New variants are now added at the bottom of the edit form instead of
at the top, with a smooth scroll and focus;
### Change requests
- On the variants diff, use variant names instead of index;
- Use an object-based diff logic (instead of array-based) for cleaner
diffs on variants (thanks @thomasheartman !);
- Display a table with the new variants data and display the diff on a
`TooltipLink`;
- Adapt strategy CR changes to the new `TooltipLink` logic for
consistency;
### Other
- `TooltipLink` and `Badge` components are now tab-selectable;
- Small enhancements, refactors and improvements;

## 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.

Includes a basic diff visualisation on variants change requests.
It seems like components like `CodeSnippetPopover` and `PopoverDiff` are
currently very tightly coupled together with strategies, so I preferred
to follow my own approach and leave those alone for now instead of
trying to refactor them. `patchVariant` could also be renamed to a more
fitting name in the future as well, since we're now doing more of an
override than applying a patch.
`Diff` is a generic diff component that uses `EventDiff` internally and
simply takes into account a "before" and "after" state, as `preData` and
`data`.
I made some changes to `EventDiff` that made some sense to me:
- Cover edge cases where `path` is undefined and `.join` crashes, also
fallback to the diff index (or undefined);
- Leverage the key to correctly sort the change items in the diff;
