fix(GRO-2342): portal waitlist card populates service {id, name}

Cosmetic follow-up to GRO-2319 (Phase 4 review by CTO). The synthetic
waitlist card on GET /portal/appointments returned service: {id} only,
so the portal fell back to the literal 'Service' label. CMPO spec did
not call for a service name on the waitlist card, but populating the
real name is non-urgent and closes the cosmetic gap.

- src/routes/portal.ts: include a services SELECT (in addition to
  pets and staff) covering both appointment and waitlist serviceIds.
  serviceMap feeds a service.name lookup. The synthetic waitlist
  card's service object is now {id, name} — same shape the
  appointments join returns — so the portal renders the real name.
  The appointments join also gains a name (consistent shape, no
  regression for the existing path).
- src/__tests__/portal.test.ts: mock the services table and assert
  service: {id, name} on both the synthetic waitlist card and the
  appointment card.
- UAT_PLAYBOOK.md: TC-API-8.20 covering the waitlist card service
  name (TC-API-8.19 retained verbatim for the original GRO-2319
  surfacing contract).
