Simplify backend configuration to HTTP only

Browse Source 
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

## Project Overview
HAProxy Dynamic Load Balancer Management Suite - a system for runtime management of HAProxy without restarts. Provides MCP interface for dynamic domain/server management with HTTP, HTTPS, and HTTP/3 (QUIC) support.
HAProxy Dynamic Load Balancer Management Suite - a system for runtime management of HAProxy without restarts. Provides MCP interface for dynamic domain/server management. Frontend supports HTTP/HTTPS/HTTP3, backends use HTTP only (SSL termination at HAProxy).
**Key Feature:** Zero-reload domain management using HAProxy map files and pool backends.

### Adding a Domain
**Default (HTTP/HTTPS/H3):**
```bash
haproxy_add_domain("example.com", "10.0.0.1")
# Creates: pool_N_1 (80), pool_N_ssl_1 (443), pool_N_h3_1 (443)
```
# Creates: pool_N_1 → 10.0.0.1:80
**Custom port (HTTP only):**
```bash
haproxy_add_domain("api.example.com", "10.0.0.1", 8080)
# Creates: pool_N_1 (8080) only
# Creates: pool_N_1 → 10.0.0.1:8080
```
This will:
1. Find available pool (e.g., `pool_5`)
2. Add to `domains.map`: `example.com pool_5`
3. Update HAProxy runtime map: `add map ... example.com pool_5`
4. Configure server(s) in pool via Runtime API
4. Configure server in pool via Runtime API (HTTP only)
5. Save to `servers.json` for persistence
**No HAProxy reload required!**
### Port Logic
| Setting | Servers Created |
|---------|-----------------|
| Default (80/443) | HTTP + HTTPS + HTTP/3 (3 servers) |
| Custom port | HTTP only (1 server) |
### Backend Configuration
- Backends always use HTTP (port 80 or custom)
- SSL/TLS termination happens at HAProxy frontend
- Each pool has 10 server slots (pool_N_1 to pool_N_10)

### Current Setup
| Item | Value |
|------|-------|
| ACME Client | certbot + dns-cloudflare |
| ACME Client | acme.sh (Google Trust Services CA) |
| Cert Directory | `/opt/haproxy/certs/` (auto-loaded by HAProxy) |
| Deploy Hook | `/etc/letsencrypt/renewal-hooks/deploy/haproxy-deploy.sh` |
| acme.sh Home | `~/.acme.sh/` |
### How It Works
1. HAProxy binds with `crt /etc/haproxy/certs/` (directory, not file)
2. All `.pem` files in directory are auto-loaded
3. SNI selects correct certificate based on domain
4. Certbot deploy hook auto-creates combined PEM on issue/renewal
4. acme.sh deploy hook auto-creates combined PEM on issue/renewal
### Adding New Certificate
```bash
# Issue certificate (Let's Encrypt)
certbot certonly \
--dns-cloudflare \
--dns-cloudflare-credentials ~/.secrets/cloudflare.ini \
-d "newdomain.com" -d "*.newdomain.com"
```
Deploy hook automatically:
1. Combines `fullchain.pem + privkey.pem` → `/opt/haproxy/certs/newdomain.com.pem`
2. Restarts HAProxy
3. **No manual cfg modification needed!**
### Google Trust Services (optional)
```bash
certbot certonly \
--server https://dv.acme-v02.api.pki.goog/directory \
--eab-kid "KEY_ID" \
--eab-hmac-key "HMAC_KEY" \

### Server Naming
Pool backends use this naming:
- `pool_N_1` to `pool_N_10` - HTTP (always created)
- `pool_N_ssl_1` to `pool_N_ssl_10` - HTTPS (default ports only)
- `pool_N_h3_1` to `pool_N_h3_10` - HTTP/3 QUIC (default ports only)
Pool backends use simple naming: `pool_N_1` to `pool_N_10`
**Examples:**
```
example.com (80/443 default):
└─ pool_5_1, pool_5_ssl_1, pool_5_h3_1
example.com → pool_5
└─ pool_5_1 (slot 1)
└─ pool_5_2 (slot 2)
└─ ... up to pool_5_10
