Claude f66c941c1d Stop the content edit dialog rewriting types it cannot represent
Opening Edit on a YouTube item and pressing Save Changes — with nothing else touched — turned it
into an MP4.

The type dropdown offers six fixed options and is rendered unconditionally. For video/youtube no
option matched, so the browser selected the first one, video/mp4. The save handler then reads the
select's value and sends it because it differs from the stored type:

    const mimeType = overlay.querySelector('#editMimeType').value;   // 'video/mp4'
    if (mimeType !== contentItem.mime_type) updateData.mime_type = mimeType;

and the server stores what it is sent. mime_type is the renderer selector in every player, so the
item became an "MP4" whose source is a YouTube embed page: a dead slide on every screen in the
playlist. It could not be undone from the dialog either, because there is no video/youtube option to
set it back, and the YouTube-specific controls disappear once the type has changed.

The same applies to uploads the sniffer accepts but the list omits — the sniffer allows fifteen
types, the dropdown covers six — so .mov, .svg, .heic, .avif and .bmp were all rewritten the same
way.

The dialog now includes the item's actual type as a selected option whenever the fixed six cannot
express it, so opening and saving is a no-op and the type is never silently changed.
