fix(doctor): strip «دکتر» prefix on IRIMC import + name-fix & purge commands

Root cause of "دکتر دکتر …" (and ellipsis-truncated "…نی") in admin: IRIMC
names already contain the «دکتر» title, while the panel renders «دکتر {name}».
Convention is to store the bare name.

- DoctorImportService: normalize name via PersianText::stripDoctorTitle
  (also fixes ي/ی, ك/ک, half-space)
- PersianText::stripDoctorTitle now strips consecutive «دکتر دکتر …» prefixes
- app:doctors:fix-irimc-names: one-off backfill for existing source='irimc'
  rows (dry-run supported) — fixed 340 rows
- app:doctors:purge: FK-safe full wipe of doctors + all dependent tables +
  orphan surrogate users, for a clean test DB (dry-run default, --force to
  apply, prod-guarded)
- tests: PersianTextTest cases for the title stripping; DoctorImportTest
  asserts stored name has no «دکتر» prefix
- docs/api/doctor-import.md: name convention + the two new commands

Verified: import "دکتر صفورا حجازی نیا" → stored "صفورا حجازی نیا" → panel
shows single «دکتر صفورا حجازی نیا».
