MINOR: stats: also report the failed header rewrites warnings on the stats page

These ones concern the warnings detected during header addition/insertion.
They are visible in the tooltip reporting the per-status codes stats. The
frontend and backend contain a total of request+response warnings, while
server only has the response warnings.
