fix(atlas): scope region name matching by country and expand country lookup tables

Browse Source 
- Fix #521: `isVisitedFeature()` now scopes name-based region matching to
  the feature's parent country (via `iso_a2`), preventing same-name regions
  in different countries (e.g. Luxembourg BE vs LU) from falsely lighting up
- Fix #489: Add ~50 missing countries to COUNTRY_BOXES, NAME_TO_CODE, and
  CONTINENT_MAP so the bounding-box fallback correctly identifies Georgia
  instead of falling through to Russia/Azerbaijan's overlapping boxes
