refactor: simplify navigation for admin portal

Remove player-facing menu items:
- Remove 'Booking' (player feature)
- Remove 'Player Lookup' (player feature)
- Remove 'Assessment' (player feature)

Update remaining navigation:
- Replace 'Dashboard' with direct link to '/admin/clubs'
- Rename to 'Venue Management' for clarity
- Simplified menu now shows only admin features
- Updated animation indices after removing items

Result: Clean, focused admin portal navigation.
