feat(club): enhance club access routes and permissions handling

- Reorganized club-related routes for better clarity and access control, ensuring specific routes are prioritized.
- Updated the store to reset user-specific permissions upon token setting, improving security.
- Modified the ClubView component to handle access checks more effectively, allowing for fallback club data when access is denied.
