Subject: [PATCH] Record browser CSP verification for SearXNG

Closes the one gap left open at deploy time. The strict CSP
(default-src 'none') had only been validated by static asset analysis,
because headless chromium produced empty output on this host and the
browser extension was not connected at the time.

Loaded the live instance in a real browser: front page, text search,
image search and autocomplete all work, and the UNFILTERED console shows
4 messages total -- all benign [PLUGIN] calculator DEBUG lines from
SearXNG's own bundle, zero "Refused to load" CSP violations. The "?"
tiles in image results are upstream 404s, not blocked requests.
