Implement logging for verification failures and enhance moderation responses

- Introduced a new logging event type `VERIFICATION_FAIL` to capture details of failed verification attempts, including reasons and actions taken.
- Updated moderation commands to include reasons in success messages for actions like ban, kick, and timeout.
- Enhanced the logging of ban and kick actions to include moderator information and reasons fetched from the audit log.
- Improved localization for new logging messages in both English and German.
- Documented changes in the phase tracking documentation to reflect the new logging capabilities and verification failure handling.
