fix(crm): offer full ISO 3166-1 country list in pickers

The country dropdown was a curated 22-entry European subset; expand it to
the complete ISO 3166-1 alpha-2 set so customers from any country can be
selected. Labels are still derived from Intl.DisplayNames and sorted by
localized name at render time, so no translation map is needed.
