- Filter header: show the active-filter count as a compact number pill instead of
'{n} active' text, and keep the action buttons on one line (shrink-0 + nowrap) so
nothing truncates or wraps in a narrow / zoomed-in sidebar (e.g. 125% browser zoom).
- Sync status: anchor the 'all synced' state with a small check icon so it no longer
reads as orphaned text at the top of the nav rail.
