fix(ui): keep panels the right rail hides itself in its layout

Exclusive presentation hides collapsed right-rail panels with display: none.
Skipping every display: none panel also skipped those, so panels the rail had
auto-collapsed stayed collapsed after the HUD was hidden or left Tactical.
Only panels hidden by other CSS are skipped now. Adds the changelog and
current-state notes.

 # Changelog
 
+- The right rail ignores panels that other CSS hides, such as during an event
+  view, so they no longer force one-panel-at-a-time layout or collapse visible
+  panels. Panels the rail collapses itself are still restored.
