Runtime verification showed the custom picker uploaded to Grav's flash but
never attached photos to the entry — attachment needs FilePond's exact
(undocumented) submit contract. Reverting to type:filepond and hooking its
beforeAddFile: a HEIC item is rejected, converted to JPEG via the lazy heic-to
chunk, then re-added with pond.addFile() so FilePond owns upload + page-attach
(the proven path). Web-format photos pass through; conversion failures fail
closed (inline status, original never added). Removes the custom photos field
template + AJAX uploader.
Verified end-to-end in a browser: HEIC posts as JPEG, corrupt HEIC is skipped,
Submit gated while converting, draft photos-reselect hint intact.
