feat(AdminController, AdminService, AdminRouter, localization): add character death cleanup feature

- Implemented `adminCleanupCharacterDeathArtifacts` method in AdminService to remove stale character-bound data after death/inheritance, including knowledge, debtors prism, and political offices.
- Added corresponding route in AdminRouter for triggering the cleanup process via an API endpoint.
- Enhanced AdminController to handle requests for the new cleanup feature, ensuring proper error handling and response formatting.
- Updated frontend components to include a user interface for initiating the cleanup, with localization support in both English and German for improved user experience.
