valknarandClaude Sonnet 5 00cc3583ec fix(traefik): stop fail2ban banning legit traffic on stray 4xx
statuscode "400,401,403-499" counted almost every client error as a
brute-force strike, so normal 404s/400s from routine app behavior could
rack up 5 hits in 10 minutes and trip a 3h ban (returned as 429) for real
users. Narrow to 401/403 (actual auth failures) and raise maxretry to 15
so it still catches real brute-forcing without false-positiving on noise.
