Case contract

Input {'res','ticket','depart' ISO local datetimes,'ap_days','ticket_within_h'}. Ticket before reservation -> 'ERR_ORDER'. AP counts calendar days between the ticketing date and the departure date (>= ap_days passes) and is checked before the ticketing time limit; ticketing must be at or before reservation + ticket_within_h hours. Return 'PASS', 'FAIL_AP' or 'FAIL_TKT_TL'.

Why this case matters

Advance purchase rules count calendar days, not elapsed 24-hour periods, and interact with a separate ticketing time limit after booking.
