Implement verification panel synchronization with BullMQ integration

- Introduced a new `verificationPanelSync` job to handle posting and updating the verification panel in Discord channels via BullMQ.
- Enhanced the `syncVerificationPanel` function to manage panel updates and error handling, ensuring proper feedback for synchronization issues.
- Updated the WebUI to support verification panel management, including improved error messages for timeout and posting failures.
- Added localization entries for new error messages related to verification panel synchronization in both English and German.
- Refactored existing verification logic to accommodate the new synchronization process, improving overall functionality and user experience.
