A tour can be a bike tour with a routing profile (touring, road, gravel,
mtb), stored per tour by a new migration. The server grades the ways of a
mountain bike route from OpenStreetMap (mtb:scale) through one shared
Overpass client, offers CyclOSM behind its own admin switch, and exports a
bike tour's GPX with the activity of its profile. A hike's route choices
are now exactly the three the card names: steep climbs, steps and ferries.
