fix(geocode): keep a leading "the" in keyless name matching

foldPlaceName drops a leading "the", so "The Hague" over upstate New
York accepted Hague, NY as an exact nearby match. Split the script-aware
fold into foldPlaceText and use it for keyless toponyms; foldPlaceName
keeps its behaviour for the packs and street matchers.

Also: changelog fragment credits #1585, folding test pins the Latin
letters NFD does not decompose (ß, ø, ł), and CURRENT-STATE notes that
non-Latin names match only when spelled with their marks.
