Each wrapper built a fresh closure every render, so `t` in a dependency array
recomputed forever. That is the documented useClient()/Jellyfin trap in
platform/CLAUDE.md, and phase 2 needs t in useMemo deps immediately.
useTranslation in officer-web now also returns tUi, typed against the shared
components' catalog. 'Cancel' and 'Close' recur across the shell and already exist
in ui.* — the alternative was importing two hooks in a hundred files.
