refactor(features): rename GetFonts to FilterAndSortFonts

The feature does not fetch fonts — that lives in \$entities/Font's
fontStore. It owns the user's filter selections, sort preference, and
search-by-name query that drive the listing. The new name describes what
it actually does.

Directory + every \$features/GetFonts import path updated; no symbol
renames in this commit.
