fix(hackathon): remove Supabase dependencies completely

- Remove Supabase export from service library
- Update forgot-password and reset-password pages to use backend API
- Update layout.tsx to use useAuthStore instead of Supabase session
- Update sidebar logout to not use Supabase
- Update middleware to use SessionUser instead of Supabase
- Update use-session hook to remove Supabase dependency
