- Wrap file-field.php validation in <form> to scope hx-include (fixes
cross-field contamination where cover change triggered note_intention
validation)
- Add inline MIME/size validation to upload-tfe-file.php
- Add inline validation to PeerTube video/audio and direct video/audio
file inputs in format-extras-block
- Fallback in validate-file-fragment-shared.php: if field_name doesn't
match any $_FILES key, try the first uploaded file (handles
PeerTube inputs where name differs from field_name)
- Fix file-field.php admin_mode using $adminMode variable instead of
undefined ADMIN_MODE constant
