fix(voice): localize the area, imagery and OSM cards and tidy OSM Places

From review:
- Card lines the actions write in English (area basis, part counts, merged
  duplicates, OSM caveats, the imagery window) are shown in the UI
  language through the analyst card's note path; the model still gets the
  English. One OSM place reads "1 hospital".
- Same-named clarification choices show their region code (WA, DC).
- OSM Places shows as unavailable once the server says no Overpass is
  configured, and its points are depth-tested past 2.5 km so they never
  show through the globe.
- find_imagery puts the operator's sources and mode back when a box is
  refused, and a voice search cancelled mid-flight leaves "Search
  cancelled" instead of an empty strip.
- The README lists OSM Places with the other Utilities.
