Enhance verification module with improved command handling and localization

- Updated the verification command to utilize a new `ephemeral` utility for consistent ephemeral message replies.
- Refactored the `buildVerificationPanel` function to include localization support for panel titles and descriptions.
- Added permission checks to ensure the bot can post in the designated verification channel.
- Introduced a new verification queue in the queue management system for better handling of verification tasks.
- Updated localization files to include new keys for verification-related messages in both English and German.
