Add global command channel rules and enhance command handling

- Introduced global command channel whitelist and blacklist in the GuildSettings model for improved command access control.
- Implemented command gate logic in the command routing to handle channel and role restrictions, providing user feedback for denied commands.
- Enhanced the CommandsManager component to support global rules and channel/role selection, improving the user interface for managing command permissions.
- Updated localization files to include new keys for global command rules and related messages, ensuring clarity in user interactions.
