Upgrade Vite and vitest dependencies to latest major version

[ashb]

Body

We are on vite 5.x and vitest 2.x which is one major version behind on each.

We should update them to the latest. I'm guessing both will need to be updated at the same time.

@ashb I’d like to take this. I can upgrade both Vite and Vitest to the latest majors, update configs/scripts, and fix any build/test breakages. If that works, please assign me this issue .Thanks!

@ashb
Using vite latest like 7.0 will lose the support of node 18
more and less, I guess it will cause some minor issue in codebase

Requiring node 22 is fine too -- it is only used during development and asset building, so we can update the min version too.

Hi @ashb — I’ve opened a PR for #55562 (Vite → v7, Vitest → v3; Node ≥22 for UI packages). Could you please review and let me know any changes you’d like?
