perf(doctor): fetch-join specialties in clinic doctor list (H6)

findByClinicWithFilters left-joined specialties only for filtering, so toListArray() lazy-loaded them per doctor (N+1). addSelect them and switch the result fetch to Paginator(fetchJoinCollection: true) so LIMIT still paginates by doctor. Test infra: ApiTestCase::countQueries() (via doctrine.debug_data_holder). Regression: tests/Doctor/ClinicDoctorListNPlusOneTest asserts the query count does not grow with doctor count (4→10 without the fix). Also relaxed AppointmentExpiryServiceTest's exact-count assertion (it counts all stale pendings in the shared db_test, which accumulates) — logged test-isolation debt as E6.
