Replace the FilePond photo path in edit mode with our own thumbnail grid that
talks straight to the media API (the gpx-manager pattern). Add/delete/reorder
each persist immediately, decoupled from the form's text-field Save:
- Add: HEIC->JPEG client-side, stock POST .../media per file, then ONE reorder
after the batch (renumber photo-01..NN). On a failed reorder: auto-retry
(idempotent), else roll the just-uploaded files back so no orphan stock-named
image breaks cover=first. Upload progress shown per file.
- Delete: inline 'Delete? [Confirm] [Cancel]' (Confirm disabled in flight),
stock DELETE, then renumber the survivors.
- Reorder: SortableJS drag -> POST /entry/<slug>/photos/order. On failure the
move reverts to last-known-good; the shown grid never disagrees with disk
without an inline error.
- Loading + empty states; first cell badged Cover; photo-NN URLs cache-busted
since reorder reuses them for different bytes.
FilePond is fully decommissioned in edit mode (initPhotoConversion early-returns
under EDIT_MODE): no stale photo_order manifest is posted on text Save, so
cache-on-save can't delete a live-added photo. Create-mode FilePond is untouched.
Adds sortablejs (bundled into js/post via the post-form entry). SVG excluded in
the file-input accept; the server-side SVG block is a documented fast-follow.
