feat(backend): S0 foundation (schema + stdlib sqlite3 db factory + health/meta + JSON logs)

- backend/db/schema.sql: all 12 tables from DATA-MODEL.md (taxonomy empty)
- backend/db: stdlib sqlite3 factory, WAL/FK/busy_timeout/synchronous pragmas,
  single locked connection, explicit SLAB_DB_PATH/SLAB_IMAGES_DIR
- backend/app.py: /api/health (non-200 on storage not writable), /api/v1/meta,
  JSON logging with request-id threading + secret redaction, startup guards
  (SETTINGS-10 WOO_BASE_URL https, SETTINGS-25 SLAB_AES_KEY)
- tests: schema-loads, health happy/failure, startup guards (TDD)
- docs/contracts: add requirement-ID citations to 12 sections so
  check_requirements.py passes (pre-existing gate debt)

Gates: check_requirements.py + check_coverage.py exit 0; pytest 5 passed
