Sebastian Krüger b420f1d4bf feat: add comprehensive Traefik security hardening ...

Added security enhancements to Traefik reverse proxy:

**TLS Security:**
- Minimum TLS 1.2 enforced
- Strong cipher suites (ECDHE, AES-GCM, ChaCha20)
- Modern curve preferences (P-521, P-384)
- SNI strict mode enabled

**HTTP Security Headers:**
- HSTS with 1-year max-age, includeSubdomains, and preload
- X-Frame-Options: SAMEORIGIN (clickjacking protection)
- X-XSS-Protection enabled
- X-Content-Type-Options: nosniff
- Referrer-Policy: strict-origin-when-cross-origin
- Permissions-Policy (disable camera, mic, geolocation, etc.)
- X-Robots-Tag for SEO control

**Rate Limiting Middlewares:**
- General: 100 req/s average, 50 burst
- API endpoints: 30 req/s average, 15 burst

**Configuration:**
- Enabled Traefik file provider for dynamic config
- Security headers applied globally to web-secure entrypoint
- Dynamic config in proxy/dynamic/security.yaml
- Auto-reloads on config changes

All HTTPS traffic now benefits from enhanced security headers.
