feat(todo): the server finds places through the instance's Photon (ADR 0033, D32)

Browse source 
Todo's locations search through the person's own instance, as Train's
planner does, not a public service: `SearchEndpoint` on `PlaceSearch`, for
those signed in, 60 searches a minute, nothing kept or logged. Its `Place`
carries the address's parts and the object in OpenStreetMap, and a shop's
car park or charger is left out, which came first for `Lindau EDEKA`.

`compose.todo-search.yaml` puts Todo's server on compose.search.yaml's
Photon. A file of its own: without it Todo starts as it did, and offers no
search.

asked for 12 so that 8 are still listed.
