fix(dashboard): appointment detail fields + sidebar hydration

- Appointment detail (DetailLg/DetailSm) read the real response shape:
  date/time from slot_start, specialty from doctor.specialties[0].name,
  phone from address.telephone.
- Sidebar Head reads userInfo (cookie) after mount to avoid an SSR/client
  hydration mismatch on the user's name.
