panel names re-render when the words behind them change

Closes the gap left by the thunk: resolving at render proves nothing is cached, but
AppPicker and PanelSlot are not subscribed to anything that changes when the locale
does, so a switch updated every string in the app except the panel titles.

An opaque revision, which this package interprets in no way at all. It is a string
that changed; the caller decides what changing means. officer-web sets it to the
active locale from I18nBridge, during render rather than in an effect — an effect
leaves the first paint after a switch showing the previous language's titles.

A module-level store rather than a prop on WorkspaceView, deliberately: that
component has 28 call sites, and a prop is a thing 28 places can forget. A forgotten
one is a silently stale title, which is the failure being closed.

The new test bumps the revision and asserts the name follows with NO rerender from the
test. The existing one calls rerender, so it could only ever prove the absence of
caching — it could not have caught this.
