fix(gui-client): migrate to tailwind v4

[thomaseizinger]

With the dependency bump in #7995, we introduced a visual regression that made all windows lose their styling:

The changelog to the v4 bump actually mentions some breaking changes and an automated upgrade tool but both the reviewer and the author of the PR missed that.

Waiting for CI to build a release binary for both Ubuntu and Windows to test.

Oh no, that's a slip up on my part. We did the same upgrade for the portal and didn't hit these issues.

I'm assuming this is now verified to look as before?

Actually we haven't upgraded in the portal yet. We'll have a similar fun time it looks like:

Thanks! I had originally set up the dev scripts so that it was easy to do the frontend dev on non-tauri platforms like macOS, but it looks like they've regressed since then. Would be helpful to get on a short call in the next couple days to see your workflow (or maybe just an updated section in README).

I just download the artifacts built in CI and install them in VMs. Not the quickest turnaround but gives me the most confidence on what the release binary will actually look like.

Same on Ubuntu:
