refactor: Unify database migrations into single initial schemas
Consolidated incremental migrations into single unified initial schema files for both procurement and production services. This simplifies database setup and eliminates migration chain complexity. Changes: - Procurement: Merged 3 migrations into 001_unified_initial_schema.py - Initial schema (20251015_1229) - Add supplier_price_list_id (20251030_0737) - Add JTBD reasoning fields (20251107) - Production: Merged 3 migrations into 001_unified_initial_schema.py - Initial schema (20251015_1231) - Add waste tracking fields (20251023_0900) - Add JTBD reasoning fields (20251107) All new fields (reasoning, consequence, reasoning_data, waste_defect_type, is_ai_assisted, supplier_price_list_id) are now included in the initial schemas from the start. Updated model files to use deferred() for reasoning fields to prevent breaking queries when running against existing databases.
