mnw-server: fix discover filter aria state and header affordances The filter sidebar's htmx:beforeRequest handler toggled only the is-selected class, so the server-rendered aria-selected went stale on the first click and then inverted: the selected item reported false while the deselected "All" still reported true. These are role=option in a role=listbox, so assistive tech reads the attribute rather than the class and the listbox announced the opposite of the screen. Set the attribute alongside the class. The column headers were gated on mode but never on view, so the default grid view rendered a five-column table header above a card grid, labelling nothing. Toggle them from applyView, which also covers the htmx:afterSwap re-apply so the header cannot drift out of sync after a filter swap. The headers also carried cursor: pointer plus a hover response while nothing bound them, inviting a click that did nothing. Sorting exists via the sort select, which made the invitation more plausible. Both rules were global, so feed.html's equally unsortable headers are fixed too.
