Move content type and ordering out of the filter sidebar into a feed toolbar (approved
proposal 2): a prominent content-type chip row (Normal/Shorts/Live toggle chips) with the
sort control + count + reshuffle in a quieter row beneath it. The toolbar renders even on
'no matches' so content-type can be turned back on after it filtered everything out. The
sidebar keeps Show / Upload date / Language / Topic; 'sort' and 'content' widgets removed
from the layout (normalizeLayout drops them from any saved layout). New feed.sortLabel
string (HU/EN/DE).
Each filter group is now a card with a collapse chevron. An Edit mode (pencil)
reveals drag handles (@dnd-kit) to reorder and eye toggles to show/hide widgets,
plus Reset to defaults. Layout (order/collapsed/hidden) persists to localStorage
and the server preferences blob, adopted on login.
