Adds cleanupOldMedia() to the storage janitor and a new endpoint
POST /api/admin/storage/cleanup-media { maxAgeDays, dryRun }.
Deletes chat attachments older than the specified threshold while
preserving profile images.
Adds getDanglingAttachments() to find attachment records whose
messageId/dmMessageId points to a deleted message. Updates stats
to show dangling count and cleanup to delete them.
- Resize avatars/icons to 256px and banners to 1280px (client crop + server safety net)
- Add server-side resizeProfileImage() for federation/API uploads without crop modal
- Fix unconstrained crop on RegisterPage and CreateSpace (was missing maxOutputDimension)
- PWA: switch to autoUpdate with skipWaiting/clientsClaim for seamless deploys
- Storage janitor: exclude profile images from unlinked cleanup, delete stale thumbnails
- Add deleteAttachmentByFilename() to clean orphaned attachment records for profile images
- Migration: one-time cleanup of stale profile image attachment records
- GeneralPanel: wrap in <form> to prevent implicit submission
- Add extension-based mimetype fallback in uploads route so thumbnail
files serve correct Content-Type (image/webp) instead of falling back
to application/octet-stream when DB lookup misses
- Skip animated images (metadata.pages > 1) during thumbnail generation
to preserve GIF/WebP animations instead of flattening to static frame
- Remove redundant explicit thumbnail deletion in storageJanitor since
deleteUploadFile() already auto-deletes the thumbnail variant
