fix(maps): stop the day route drawing drives to airports you flew from

A flight leaving overnight contributes only its departure airport on the day
it leaves, and the evening hotel bookend was attaching to whatever point sat
at the day's edge. So the map drew a straight line from the airport you took
off from to the hotel you were checking into.

The same blind spot on the run builder produced the long rays: a day's order
is a bare wall clock, so an inbound long-haul whose departure clock reads late
sorts after the day's local stops, and its far departure airport got appended
to that run. OSRM answers such a pair with NoRoute and the fallback straightens
the whole chunk, taking the genuine local drive with it.

Both now ask whether the pair could be driven at all. A flight, train, ferry,
cruise or coach carries you out of the day's geography, so its departure point
has no drive back to tonight's hotel and its arrival point had no drive from
this morning's. A hire car is the opposite and stays out of that set: you keep
driving it, so a multi-day rental's pickup and drop-off points keep their hotel
legs. Alongside it, any leg touching a booking endpoint has to be within
MAX_DRIVE_KM, which catches the mis-sorted edges the role alone cannot see.

The sidebar gets both guards so its hotel connectors stay in step with the
drawn route; the mobile map and timeline read the same hook.
