- /search and /reading-list already had Header + Footer; add a
single in-content 728x90 banner at the bottom of each main column
(gated on ADS_728X90.length > 0, hidden on mobile).
- /contributor was a bare dashboard with sidebar + main, no site
chrome at all. Wrap it in the standard Header + Footer; drop the
inner sidebar/main wrapper from min-h-screen to a natural-height
flex so the dashboard sits below the header instead of competing
with it for full viewport. Header brings the site-wide 728x90
leaderboard with it, so contributors see the same ad inventory
as the public site without a second in-content banner cluttering
the dashboard panes.
