Remove SSL/QUIC backend templates - all backends now use HTTP only
with SSL termination at HAProxy frontend. This improves performance
(~33% faster than HTTPS backends based on benchmarks).
Changes:
- server.py: Remove https_port parameter from all functions
- haproxy.cfg: Remove ssl/h3 server templates from pool backends
- CLAUDE.md: Update docs for HTTP-only backends and acme.sh
