[EPIC-001-FK-DEBILES] feat(ddl): Add conditional FK constraints to fix weak references
Add 19 conditional FK constraints to 4 schema files: - 06-inventory-ext: 7 FKs (warehouses, products, uom, stock_moves) - 07-purchase-ext: 5 FKs (purchase_orders, partners, products) - 03-hse: 3 FKs (almacen_temporal for EPP) - 10-documents: 4 FKs (documents, users) Features: - Constraints are conditional (only created if target tables exist) - Idempotent (can be re-run without errors) - Added 6 new indexes for FK fields Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
