fix(appointment): render real slot structure in time picker

The slots API returns data.sessions[].slots[] with start_time (HH:MM),
is_available, and start/end unix timestamps — not the morning/evening +
time/status shape the UI assumed. Add lib/appointmentSlots.js to flatten
sessions into morning/evening by start_time, fetch with doctor.uuid, and
read item.start_time / item.is_available in the slot grid. Derive the
clinic address from the already-loaded doctor.address by location_id
instead of a separate auth-required call.
