feat(tours): bike tours in the planner, CyclOSM, and the planned cards' last points (BIK-01 to BIK-06, RTE-01, IO-01, LIB-02)

The tour type is a dropdown; a bike tour picks its profile, routes for it,
says when a point lies off every way, and shows what it runs on: surfaces,
kinds of way and, for a mountain bike, the trail grades, each pointed at on
the map. A type's own map (OpenHikingMap for a hike, CyclOSM for a bike tour)
is offered while a tour of that type is open, with an admin switch each.

From the planned cards: a hike avoids steep climbs, steps or ferries, nothing
else; a saved tour can be shared where the platform takes GPX files; and the
tours rail adds a tour from one menu: plan new, import GPX, or take one over
from another trip.
