feat(doctor): claim-profile section + modal for unclaimed IRIMC-imported doctors

- ClaimProfileSection (components/doctor/claim): shown only when
  doctor.owner_status === "unclaimed"; banner explains the profile is not
  yet managed by the doctor, button "تأیید و مدیریت این پروفایل"
- Modal: login prompt when logged out; otherwise first/last name,
  national code, Jalali birth-date (existing JalaliDatePicker) — posts to
  POST api/v1/doctor/{uuid}/claim (identity verified server-side via API.ir;
  no client call to API.ir, no token exposure)
- States: loading, per-field validation, server error (Persian envelope
  message), double-submit guard, success welcome message + redirect
- Shared component across main domain and all representative subdomains
- services/response.js: getDoctorClaimInfo / postDoctorClaim
