refactor(frontend): drop unused params, props and api surface

Remove the never-read _revalidate argument of mutateVerge and its 16
call-site placeholders, seven never-passed props of the split chip
editor, the unconsumed refreshDecorated context member, the now-orphaned
toggleFullscreen control, the unused translate argument of the notice
message handler, the reserved-but-unset ServiceConfig.timeout field and
unreachable branches in parseNoticeExtras.
