fix(portal): GRO-2203 validate petId as UUID before PATCH lookup (500→404)

A non-UUID :petId passed straight into where(eq(pets.id, petId)) made
Postgres throw "invalid input syntax for type uuid", surfacing as an
unhandled 500. Guard the param with z.string().uuid() and return the
existing 404 {"error":"Not found"} for malformed ids, mirroring the
GRO-2014 fix in pets.ts. Valid-UUID-not-found already returned 404.

- Add regression test (non-UUID petId → 404, no mutation)
- Update UAT_PLAYBOOK.md §8 (TC-API-8.16)
