4. Reserve a seat (one at a time)

In plain words: “lock this seat for ~12 minutes while the customer pays.” One seat = one reservation. Two tickets = two reservations (same kind of call twice with different seats). Save each reservation number (hold id).

Send: only seat_id (seat number). Example for 2 seats: call twice with two different seat_ids.

{
  "seat_id": "73660"
}

Seat reserved — keep hold.id for confirmation
