refactor(quota): migrate traffic quota from tunnel to user level

- Replace tunnel_quota table with user_quota table
- Add user-level daily/monthly quota tracking and enforcement
- Update user CRUD to include quota configuration
- Migrate backup/restore to use user quota fields
- Update frontend API and UI for user quota management
