semianiakavy 8c6236c8f1 feat(db): schema, migrations and idempotent seed for the catalog
Implement the data layer from docs/PLAN.md §4 (card #55):

- db/migrations/0001_init.sql: idempotent DDL for the 16 entities (category,
  product, product_category, product_image, product_variant, product_feature,
  cart, cart_item, customer, address, orders, order_item, payment, promo_code,
  content_page, delivery_option) with relations and indexes; explicit index on
  orders.number (product.slug/category.slug are unique-indexed by their keys).
- Currency BYN (R4/Q1): STORE_CURRENCY = 'BYN', money as integer minor units
  (BYN * 100), no float, no interim currency, no FX conversion.
- Idempotent seed: 14 categories (11 visible + 3 hidden visible=false, R13) and
  93 products from docs/CATALOG.md §3 (broken #59 excluded, R14) with prices,
  old prices and badges; cross-listing, images, variants, PDP fields (R9),
  store constants (CATALOG §6), 1 admin + 1 customer and 2 orders.
- scripts/{migrate,seed,verify}.ts + src/db: CLI entry points and an in-process
  Postgres verification harness (satisfies `migrate` + `seed` on a clean clone).
- db/seed/0001_seed.sql: generated single-file SQL for the platform Data Tables
  (`/db-forms`, run_sql) to converge tenant_1 without a Node process.
- Placeholder dev server + storefront currency/constants and money helpers.

Verified on a clean Postgres (PGlite): product = 93; category = 14 with
visible = 11; orders = 2; money integer BYN minor units (0 float rows).
