The last behavior gap in the H2 batch: has_conflict was part of the
frozen card shape but stamped false-forever on these three JSON
surfaces (only dashboard sections, search, and the SSR pages had it),
so every conflict-driven card action — the resolve-conflict CTA in
BookCard — never fired there. MarkActiveConflicts now runs after the
builder on GET /api/collections/:id, series books, and smart-collection
preview (all user-scoped; the endpoint already authenticates).
Key set is unchanged — has_conflict was always emitted, this only
makes its value truthful. All 15 contract pins + H1 tests green; the
pin's bookInfoKeys freeze unaffected.
