feat(todo): the map keeps its size, the search a screen of its own (ADR 0033, D32)

From the developer's trial of the picker. Below a medium width a sheet
of fixed height sits under the map, whatever is around the pin, and is
pulled up over it for the whole list, as Threema's; a landscape phone or
a wider window has it as a pane beside the map. The search opens its own
screen: name, what it is, where it lies and how far. A compass under the
bar turns the map to north, and my position no longer zooms out.

A pinch only zooms unless the fingers turn first, the pin's shadow lies
on the map's middle, and a look around that failed says so, with Try again. It asks
little: after the map rested, one at a time, nothing for a spot answered
or by zooming, and nothing for 30 seconds after a failure, as komoot's
Photon throttled a person moving the map about.

Fixes the wrong map for the theme: OpenFreeMap's styles name themselves
nothing and the tile cache goes by that name, so a theme got the other's
tiles (seen on an emulator, both ways); each now has its own name.

Whats-New: The location map keeps its size, the list of places pulls up over it, and search opens its own screen with kinds and distances.
Whats-New-De: Die Ortskarte behält ihre Größe, die Ortsliste lässt sich über sie ziehen, und die Suche öffnet sich als eigene Seite mit Art und Entfernung.
