- Add UAT_CLIENT (name: "UAT Customer", email: uat-customer@groombook.dev,
phone: 555-0100, address: 1 UAT Lane, status: active)
- Add UAT_PETS: Bella (Poodle, curly) and Max (Labrador Retriever, short)
- Add idempotent UAT Client upsert block and UAT Pets loop after Demo Dog
- Change adminSeedRouter.post("/seed") → adminSeedRouter.post("/") so the
mounted path is /api/admin/seed (not /api/admin/seed/seed)
Fixes the build-path mismatch where the Dockerfile's COPY src/ src/ would
not include the UAT data changes that were only in apps/api/src/.
