chore: remove unused packages, imports, and stale type definitions

- Remove @casl/prisma (unused) from backend
- Remove @heroicons/react (unused, using lucide-react) from frontend
- Remove unused InferSubjects import from ability.factory.ts
- Remove unused Calendar import from Dashboard.tsx
- Delete stale frontend/src/lib/types.ts (duplicate of src/types/index.ts)
