chore: migrate Vite config to Vite 8 beta (Rolldown) (#8152)

Prepares Vite config for Vite 8 by migrating from esbuild/Rollup to
Rolldown/Oxc.

## Changes
- Migrate `build.rollupOptions` → `build.rolldownOptions`
- Replace `manualChunks` with `codeSplitting.groups`
- Update Storybook config with `strictExecutionOrder` for module loading
compatibility

## Testing
- [x] `pnpm typecheck` passes
- [x] `pnpm build` succeeds
- [x] `pnpm test:unit` passes
