feat: picture modal hero panel with image preview

Adds a split-layout hero section at the top of the RecordModal
for pictures: left side shows the image preview (~40%), right side
shows status, design (both editable) and the linked words relation
manager inline. Remaining fields (blurhash, picture_link, metadata)
continue to appear in the sections below.
