fix(voice): resolve areas per view, without accents and per natural place

From review:
- An answer the view picked ("Springfield" over Illinois) is reused or
  shared only within the same ~2° view cell, so asking again elsewhere no
  longer gets the first state's area.
- Admin names compare with accents folded on Latin letters only: "Quebec"
  matches "Québec" and "Cordoba" asks between Argentina and Spain, while a
  Thai or Devanagari mark still tells names apart.
- A Natural Earth name used by several features is one place with every
  part when they touch (the Great Rift Valley, the Lau Group across 180°)
  and a question when they are far apart (Flores); natural places can now
  be candidates.
- The AREAS rule and the area tool descriptions are tighter, leaving a
  ~270-character margin under the 55,500 prompt ceiling, and resolve_area
  no longer names osm_query when that tool is not offered.
