Add Charades word lists management, profanity filter, and matchmaking routes (#41)

* feat: add 3D Charades word lists management and profanity filter toggle

- Implemented Charades word lists management in the admin UI, allowing for unlimited named word lists with difficulty settings.
- Added functionality to bind live card slots to specific word lists, with automatic fallback to built-in lists.
- Introduced a profanity filter toggle in server settings, enabling or disabling the server-side profanity filter.
- Updated database schema to support new features, including additional columns for profanity filter status and charades slot bindings.
- Enhanced documentation to reflect new features and their usage.

* feat: add identityserver-signing.pfx to .gitignore

* feat: add new matchmake routes for player, event, club, and code
