- Live stops polling on a failed read and marks the list as possibly
stale (with Retry), instead of re-raising the error dialog every tick.
- While live, a refetch reads the newest page only, whatever the cache
holds (a late "Load older", a revisited filter set).
- Copy is disabled and the list dimmed while a filter change loads.
- Dates follow the UI language; the pivot chip uses the shared .chip.
- Tests: query-string wire test, Copy, every facet's skip key.
