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.
