feat(doctor): complete IRIMC import feature — claim flow, least-privilege importer, unique import key

- Extract import logic from AdminApiController into DoctorImportService
  (thin DoctorImportController keeps the same route/contract)
- Surrogate users get marker role ROLE_UNCLAIMED_DOCTOR (+ backfill command
  app:doctors:backfill-surrogate-role) enabling safe deletion after claim
- DB-level UNIQUE (source, medical_system_code) + concurrent-import retry
- Doctor profile claim flow (climed.md): shahkar + PersonInfo identity checks
  via existing ApiIrService, Persian name normalization (PersianText),
  pessimistic-lock race protection, DoctorClaimRequest audit table
  (national code hashed, mobile masked), doctor_claim rate limiter,
  public claim-info endpoint, welcome SMS
- Admin support tools: manual transfer endpoint + paginated doctor-claims
  audit list + owner_status filter/fields in admin doctors list
- Least privilege: system owner now gets ROLE_IMPORTER (ROLE_ADMIN stripped),
  import endpoint accepts ADMIN|IMPORTER, isStaff includes IMPORTER
- Headless crawler login: X-Service-Token header bypasses captcha only
  (rate limit + password checks intact; empty env = no bypass)
- docs: doctor-claim.md (new), doctor-import.md, admin.md, doctor.md
- tests: DoctorImportTest (6), DoctorClaimTest (11), PersianTextTest (5)
