Implement lockdown management in automod system

- Added functionality to activate and deactivate lockdowns via the automod worker, responding to specific job names.
- Enhanced the anti-raid join handler to apply a verification role when lockdown is active and the anti-raid action is set to VERIFY.
- Updated the automod configuration to ensure default rules are created if missing, improving the setup process for new guilds.
- Introduced new API endpoints for managing cases and warnings, allowing for soft deletion and reason updates.
- Enhanced the moderation dashboard to include warnings management, improving user experience in moderation tasks.
- Updated localization files to reflect new features and improve user guidance in both English and German.
