The backend test was hanging in CI because server.js imports off-service.js
which pulls in redis-client.js. Without a mock, it tries to connect to Redis
at import time, hanging indefinitely in CI where no Redis server exists.
Also added the missing searchOTC mock for cima-service.js to fix the
SyntaxError from the export mismatch.
- transformOFFProduct: maps OFF products to unified Product model
- searchBabyProducts: searches baby products via OFF API (1h cache)
- getBabyProductDetails: fetches product details by barcode (1h cache)
- 9 tests passing for transform logic and input validation
