Galleries can't be fully moderated

[tassoman]

💡 Summary

Gallery feature is lacking of an important feature, ability for moderators and administrators to delete pictures 1 by 1 from galleries (cherry trash 🍒🧺). Or editing unwanted texts. They can only delete the entire galleries.

🥰 Expected Behavior

• as admin / mod I want to edit a gallery by deleting just one or more images.
• as admin / mod I want to edit texts of galleries (title and description)
• as admin / mod I want to set gallery as sensitive NSFW
• as admin / mod I want to act on every gallery in my server
• gallery should link a button to original file into user's drive, so that admin/mods can delete it during moderation operations

🤬 Actual Behavior

• admin / mods can only delete entirely a gallery
• admin / mods can't set sensitive gallery
• admin / mods can't edit gallery's texts
• when images are marked sensitive (as drive files) they are not blurred, as already happen while Note's attachment

📝 Steps to Reproduce

1. install 2025.11.2
2. as user create a gallery
3. put 3 images into gallery
4. save the gallery
5. login as admin
6. browse to galleries
7. see: no way to edit this gallery, only trash button can delete the gallery.
