feat: add feedback management enhancements

- Add German translations for event dropdown menu actions
- Add feedback settings to event edit form
- Hide comment button in gallery when feedback is disabled
- Add feedback moderation panel to event details page

Implements:
1. German translation for three dots menu actions (viewDetails, archiveEventAction, etc.)
2. Feedback enable option now visible when editing existing events
3. Comment button in photo lightbox only shows when feedback is enabled
4. Inline comment moderation in admin event detail view
