i18n(voice): tighten the geometry translations after a second review

- keep inserted place names clear of prepositions and articles they
  would need in fr, pt, ru and uk
- use each catalog's own terms: punto de interés, trazar contorno,
  Buscando, 加載/匹配/搜索 and full-width colons in ja
- list the Italian "Area" as intentionally the same as English
