fix(listview): match Explore Select dropdown height + fix clear-all after refresh

CompactSelectPanel: remove overflow:hidden from panel (was clipping search
input); remove min-height from OptionItem (5px padding alone gives the
correct 24px height matching AntD Select optionPadding, not 42px).

index.tsx: clearFilters/clearFilterById now call updateFilterValue directly
as a safety net so URL always updates even when filter refs are stale
(e.g. after page refresh where internalFilters is URL-hydrated).
