V001: pgcrypto + citext extensions, trigger_set_updated_at function.
V002-V019: tables in FK dependency order per data model v1.1.
Spec fixes incorporated:
- recipe: added created_at/updated_at (spec says all mutable tables
carry audit timestamps, but ERD omitted them)
- shopping_list: added household_id FK for HouseholdContext scoping
- shopping_list_item: added checked_by FK (API returns checkedBy)
- cooking_log: omitted phantom week_plan_slot_id (in FK map but
absent from ERD, API, and all journeys)
