refactor(GetFonts): consolidate model/state into model/store

Align the slice with the project-wide convention (entities/Font,
entities/Breadcrumb, features/ChangeAppTheme all use model/store/;
CLAUDE.md spec calls for store/). Move bindings, filters, and the
filterManager subdir out of the now-removed model/state/ directory.
