The passport card and the last/next trip countries read place countries
from the place_regions cache alone, while the Atlas map falls back to the
bundled borders for a place without a cached region. A place in Vatican
City never gets a region row (the region bundle has no VA features and
Nominatim names no region there), so the map counted VA and the card did
not. The same gap hid any country whose place was still waiting for its
background lookup, or whose lookup had failed.
Both views now resolve each place through one helper: the cached country
first, the borders otherwise, once per location. The dashboard reads every
place of a started trip with its cached country instead of the distinct
cached codes, and the trip countries count resolved places the same way.
The MCP travel stats tool and the public stats API use the same service
methods and are fixed with it.
