A new `integrations/dawarich` domain behind its own addon. Each reader
connects their own instance; the API key is encrypted at rest and never
returned. Nothing is written back to Dawarich, and no raw position is
kept in TREK: the recorded route is fetched per request for the window
being looked at and thrown away again.
What it produces are suggestions, never facts. A recorded stay becomes a
proposed place or journal entry, a country or city becomes a proposed
Atlas mark, and a stay near a wish becomes a proposed tick-off; each one
waits for the reader to confirm it. Identity is (user, Dawarich visit),
so a second sync neither duplicates nor overwrites what was accepted,
and deleting the result puts the suggestion back on the list.
The sync runs as a job on the central scheduler, one user at a time,
guarded against overlapping runs.
