fix: resolve pre-existing test and TypeScript errors for CI compliance

- Fix CLIENT_ID/PET_ID in petsExtendedFields.test.ts to valid UUIDs so
  createPetSchema validation (z.string().uuid()) passes in tests
- Replace top-level imports of and/eq/exists/or with vi.fn() stubs in
  petsExtendedFields.test.ts mock to avoid vi.mock hoisting ReferenceError
- Add impersonationAuditLogs proxy + insert() chain to portal.test.ts mock
  to fix audit-log write failures
- Add 5 missing extended fields to buildPet factory defaults
- Add non-null assertion on petRows[0] in makeDeleteChainable
