slab_photos.id is a global primary key and photo ids are derived from the slab
id, so scoping the replace to the slab let a retried or concurrent upload of
the same draft hit UNIQUE(id) and 500. Clear the id unconditionally.
REVIEW-5 / PUBLISH-45: owner edits the stored photo lineup in Review — tap a
card to keep/remove, drag to reorder, leftmost kept photo = primary (Woo
cover). The kept set must contain a clean calibration + its dimension-overlay
copy; publish is blocked until it does.
- backend: role column on slab_photos (schema + idempotent _migrate ALTER),
role in photo CRUD + new DELETE endpoint, Woo image order by role-rank
(clean→overlay→batch) per PUBLISH-45
- frontend: Review photo strip (render from listPhotos, keep/remove,
HTML5 drag-reorder, dynamic PRIMARY badge from .primary class),
persistLineup() re-seq kept + drop removed before entering Publish
- tests: lineup.ts unit, e2e review-photo-strip.spec, backend role + order
