feat(patient): complete "اطلاعات پرونده" demographic form

Backend:
- Add profile columns field_of_study, province_id, city_id, postal_code,
  referral_source (UserProfile + migration).
- Extend PATCH /api/v1/patient/{uuid} to persist all demographic fields
  and return them in the patient profile payload.
- Support editable mobile (login identifier): validation, uniqueness,
  User.setMobileNumber, new ERR_PROFILE_002.
- Update docs/api/patient.md.

Frontend:
- New reusable Input, Field, and PatientRecordInfoForm (RHF + Zod).
- usePatient/useUpdatePatient hooks and patientForm mapping helpers.
- Extend the existing "info" tab in MyPatientsPage to the full field set
  via the shared form (province/city/insurance options, Jalali date).

Tests: Patient entity + PATCH integration (PHPUnit); form, hooks, and
mapping helpers (Vitest).
