Fixes: #21039

Preserve .avif extensions when uploading Image Attachments (so the attachment is served with the expected filename), and ensure AVIF files are selectable in the UI.

Add AVIF (.avif / image/avif) to the list of acceptable image extensions used when generating attachment filenames, so the stored file keeps its extension.
Update the image upload widget to explicitly include AVIF in the accept attribute (required for Firefox to offer AVIF files in the file picker).
Manual test: upload a AVIF file as an Image Attachment and confirm it’s served at /media/image-attachments/...avif.

Thanks for the review!
