CLAUDE: Add /admin-clear-scorecards command for manual channel management

- Added new admin-only command to manually clear #live-sba-scores
- Clears all messages from the channel (up to 100)
- Sets @everyone view permission to False (hides channel)
- Bot retains access via role permissions
- Provides detailed feedback on operation success
- Updated /admin-help to include new command

Use cases:
- Manual cleanup of stale scorebug displays
- Testing channel visibility functionality
- Emergency channel management
- Forcing channel to hidden state
