feat(mantine): upgrade @mantine/core and @mantine/hooks to v9.0.2

Upgrades the @blocknote/mantine peer dependencies from Mantine v8 to v9
following the official 8.x → 9.x migration guide.

- Bump @mantine/core, @mantine/hooks to ^9.0.2 across all packages,
  examples, playground, docs, tests/nextjs-test-app and the example
  template in dev-scripts
- Drop unused @mantine/utils v6 dependency
- Fix Loader ref-type regression: v9's Mantine Loader renders as an
  <svg>, so wrap it in a forwarded <div> in SuggestionMenuLoader and
  GridSuggestionMenuLoader to preserve the HTMLDivElement ref contract
- Update template vite to ^8.0.3 / @vitejs/plugin-react to ^6.0.1 so
  regenerated examples no longer downgrade vite on gen:examples
