Fix type errors, lint, and complexity from VPS architecture cleanup

- Fix brand-to-Convex-Id casts in use-project-workspace (as unknown as)
- Extract ProjectsLoading and ConnectProject components to drop SliceOnePage
  complexity below the lint threshold of 20
- Fix formatting in project-requests.ts
- Archive orphaned standalone chat files (route removed, referenced dead env)
- All 8 packages typecheck clean; 31 web tests pass; root check clean
