HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m33s
Add rate limiting, connection limits, and timeout hardening
Activate HAProxy's built-in attack prevention to stop floods that cause
the container to become unresponsive:

- Stick table tracks per-IP: conn_cur, conn_rate, http_req_rate, http_err_rate
- Rate limit rules: deny at 50 req/s, tarpit at 20 req/s, connection
  rate limit at 60/10s, concurrent connection cap at 100, error rate
  tarpit at 20 errors/30s
- Harden timeouts: http-request 300s→30s, connect 120s→10s, client
  10m→5m, keep-alive 120s→30s
- HTTP/2 Rapid Reset protection (CVE-2023-44487): stream and glitch limits
- Stats frontend on localhost:8404 for monitoring
- HEALTHCHECK now validates both port 80 (HAProxy) and 8000 (API)
