Migrate from Vite to RsPack

[NaucMeIT]

Reason

Vite is broken with Semi Design (our UI library of choice) and it is so much pain in the ass that it just isn't worth it.

Steps

1. Decide if it's better to clone this example: https://github.com/TanStack/router/tree/main/examples/react/quickstart-rspack-file-based into apps/coursition-rs or init new app (via pnpm create @tanstack/router) pick RsPack and follow next steps.
2. Migrate apps/coursition content.
3. Make sure all libraries (@tanstack/react-query, @tanstack/react-query-devtools, @tanstack/react-router, @tanstack/react-router-with-query, @tanstack/router-devtools) work well and app starts.
