Add a dedicated SearchController that matches the query against video
title / description / tags / primary language AND any secondary audio
track language (so "arabic" surfaces videos that carry an Arabic track
even if the primary language is English), plus channel name / username
/ bio, plus playlist name / description. Public visibility only.
Results reuse the videos/index view so every card gets the same
component the browse feeds use. A new Channels section renders above
the Videos grid when channel hits exist.
/videos/search is kept as a 301 redirect to /search so bookmarks and
external links stay valid; both the desktop header and mobile overlay
search forms now point at the canonical route, both carry a visually
hidden <label>, both get role="search" and both preserve the current
query in their input.
