The Browse tab nav scrolled away (operator didn't know it existed) and
Posts had no search. Roll the tab strip + a shared search field into one
sticky block pinned under the 64px TopNav.
- Posts gains server-side text search: PostFeedService.scroll()/around()
+ /api/posts accept q (ILIKE over post_title OR description), applied
INSIDE the artist/platform WHERE so search stays scoped to the active
filter. Scope shown as clearable chips next to the search field.
- Artists/Tags search consolidates into the sticky bar: their inner
search boxes are removed; they react to route.query.q (q is deep-
linkable, e.g. /browse?tab=posts&q=foo). Platform/kind filters stay.
- Posts empty state now distinguishes 'no matches' from 'no posts yet'.
Tests: posts q-search matches title|description and stays artist-scoped
(service); q passthrough (api).
