/**
 * Unit tests for the DI-native CollectionsService (COLLECTIONS-SVC-001 … 092;
 * moved 1:1 from the legacy tests/unit/services/collectionsService.test.ts,
 * case IDs preserved — the 080/081 membership-lookup cases are new with the
 * fold, and the 090–092 band pins the post-fold quirk fixes: all-or-nothing
 * bulk writes and socket-id forwarding on the from-trip saves). Real in-memory SQLite (full schema + migrations) so the SQL —
 * owner/member visibility, the collection-scoped dedup, the fusion state
 * machine and the widened photo-cache reference check — is exercised
 * faithfully. Keeps its own clearCollections() reset (the shared
 * resetTestDb RESET_TABLES list has no collection tables).
