feat(Moderation): enhance moderation reporting and user feedback

- Added user blocking checks in authentication and reporting processes, returning appropriate error responses.
- Expanded moderation report functionality to include new target types and optional fields for reports.
- Implemented a new API endpoint to retrieve the count of open moderation reports.
- Enhanced frontend components to allow users to report profiles, images, and guestbook entries, with corresponding UI updates.
- Updated internationalization files to include new strings for reporting features in both German and English.
