feat(patients): drop phone/dateOfBirth, name fields optional

Reduced the patient record to the minimum a dental clinic actually needs:
just a code, optional first/last name and free-text notes. Phone and
date-of-birth fields are gone from the UI everywhere — Add form, edit
dialog inside the table, the Bağlantı Bilgileri block on job detail, and
the table column list. The patient list now surfaces 'Notlar' instead.

Backend
  - DB: firstName and lastName columns set to required=false via Appwrite
    MCP (tables_db_update_string_column). Existing rows untouched.
  - schema.ts Patient interface: firstName/lastName now optional, phone
    and dateOfBirth removed from the type entirely. The underlying columns
    are still in the DB so legacy rows aren't broken — we just stop
    referencing them in code.
  - validation/patient.ts: firstName/lastName drop min(1), phone and dob
    fields removed.
  - patient-actions.ts: pickFields no longer reads phone/dob, create and
    update payloads no longer write them.

UI fallbacks
  - PatientsTable: header has 'Notlar' instead of Telefon/Doğum. Ad Soyad
    cell shows the joined name or em-dash. Edit dialog mirrors the same
    simplified form.
  - jobs/[jobId] detail page: when patient row has neither name, the page
    title falls back to 'Hasta {patientCode}' (same as before for jobs
    without a linked patient). The Hasta Bilgileri card now shows Ad Soyad
    and Patient Code side by side, with notes spanning both columns.
