1) Move the Show view filter (Unwatched/In progress/All/Watched/Hidden) up into the
toolbar chip row as its own single-select group, divided from the content-type chips;
removed the 'show' sidebar widget (sidebar now = Upload date / Language / Topic).
2) Rework ordering like the Playlists page: a sort-key dropdown (Date, Popular, Duration,
Name, Channel subscribers, Channel priority, Surprise me) + a single asc/desc arrow
toggle, instead of separate directional entries. 'Most viewed' is now 'Popular'.
Backend gains the missing directions (views_asc, title_desc, subscribers_asc,
priority_asc); the frontend maps (key, dir) -> the backend sort string, so FeedFilters
is unchanged. Trilingual (feed.sortKey.*, feed.dirAsc/dirDesc). Feed.tsx normalized to LF.
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.
