-- Mejora #9: Caché de Stock con Redis
--
-- Adds Redis-backed stock caching for sub-millisecond lookups.
-- No database schema changes required — caching is handled entirely
-- in the application layer (pos/services/redis_stock_cache.py).
--
-- Invalidation strategy:
-- - Every stock mutation (SALE, PURCHASE, RETURN, ADJUST, TRANSFER, INITIAL)
-- invalidates the affected Redis keys immediately in Python code.
-- - Cache TTL is 5 minutes (configurable via REDIS_STOCK_TTL env var).
-- - On Redis miss, stock is computed from PostgreSQL SUM query and cached.
--
-- Prerequisites:
-- - Redis server installed and running (default: localhost:6379)
-- - redis-py library installed

5. Restore tenants:
