feat(appointment): real for-another-patient form and booking payload

Replace the mock for-another button with a real toggle: switching keeps
the user's own data, clears the form to editable patient fields (phone
becomes an input, adds علت مراجعه), and can switch back. SubmitData now
sends for_self plus patient_* only when booking for someone else, skips
the self-profile PATCH/POST in that case, stores the booking expires_at,
and surfaces a clearer 409 message. Thread appointmentExpiresAt through
the wizard to the payment step.
