feat(client): show Dawarich stays, routes and marks where they belong

The trip planner and the journal get a "From Dawarich" list: the stays
recorded for those dates, each one a row that can be dismissed or turned
into a place or an entry after a review step that shows time, name, note
and day. A place that came from a recording carries the Dawarich mark
next to its name so its origin stays visible afterwards.

The recorded route lies over the trip and journal maps as an overlay,
coloured per day and cut along the reader's own timezone rather than
UTC. It is fetched for the window on screen and never stored.

The Atlas gets its own panel beside the map for the countries and cities
the recordings prove, and the wish list is ticked off there, on the day
of the visit, undoably. The phone has its own take on all of it, in the
mobile shell's colours and with native sheets.
