"""
Phase 1 — Step 1.7: crm_quotation_items (SQLite → Postgres)
FK to crm_quotations(id) — quotations must be migrated first (step 1.6).
FK enforcement suppressed via session_replication_role for the same reason
as in migrate_crm_quotations (parent crm_customers not yet in PG).
Run on VPS:
docker compose exec backend python -m migration.migrate_crm_quotation_items
