feat(pets): add GET /:id/profile-summary endpoint

Adds profile-summary endpoint for groombook web to display:
- Basic pet fields (name, species, breed, coatType, etc.)
- Recent grooming history (last 10 completed appointments with staff names)
- Visit count (completed appointments)
- Upcoming appointment (next scheduled/confirmed)

Groomer RBAC: groomers can only see pets they've had appointments with.
Non-groomer staff (admin/super) can see all pets.

Fixes GRO-1802 (UAT regression: profile-summary route never deployed).
