Merge main into codex/graphic-attributes-cleanup

Conflicts were additions on both sides, kept together: the Count palette
and Sheet Set toggles next to the Graphic Attributes toggle in the ribbon,
main's new locale groups and catalog entries next to graphic-attributes,
and module declarations. The palette code follows main's crate renames
(acadrust -> codec, cadkernel -> kernel).
