feat(composer): fit footer controls by overflow (#4657, rebased onto master)

Rebased Paladin173's #4657 onto current master. The per-control visibility
toggles half already shipped via his own #4598, so this rebase carries only the
net-new JS fit-by-overflow engine (_fitComposerFooter: ResizeObserver +
MutationObserver measure .composer-left overflow, step full -> cf-icons ->
cf-burger). Co-authored-by: Paladin173 <Paladin173@users.noreply.github.com>
