Convert raw inserts to upserts (ON CONFLICT DO UPDATE) for:
- staff: upsert on email (unique constraint)
- services: upsert on id (deterministic UUID)
- clients: upsert on email (unique constraint)
- pets: upsert on id (deterministic UUID)
This fixes the duplicate key violation when re-running the seed
script against an existing database (e.g., after schema migrations
or test restarts).
Note: appointments, invoices, visit logs still use raw inserts
and would need DELETE-before-insert for full idempotency. Those
tables use deterministic UUIDs so a second seed run without
prior DELETE would still fail. This is scoped to the immediate
staff email constraint violation reported.
