Split into copies: the symmetric partner of the merge veto

Three identical boxes in three photos are indistinguishable from one
box photographed three times, so extract's dedupe folds them into one
entry — correct for overlapping shots, wrong for a shelf holding three
editions of a favorite game. The catalog now offers "split into copies"
on multi-photo rows: the row explodes into one row per photo, each
dedupe_veto-flagged so no future resolve re-merges them, each keeping
its match but reopening its own edition slot (candidates preserved when
present). Resolve's provenance-follow skips split rows (their photo
sets are human-authored), the catalog renders surplus split copies as
their own lines with a "copy" chip, and diff's vetoed-duplicate logic
turns them into the extra collection entries they are.

Applied to the real data: Wiz-War is now three copies across IMG_4502/
4504/4528 — one claims the owned collection entry, two queue as new
second-copy adds.
