Configure Traefik for public-facing access with frostlabs.me domains

- Fixed certificatesResolvers configuration in static.yml (moved out of tls section)
- Added DNS resolvers to Cloudflare ACME challenge configuration
- Added persistent volume mount for Let's Encrypt certificates
- Updated Outline service labels to use flow.frostlabs.me with proper cert resolver
- Updated Authentik service labels to use auth.frostlabs.me with proper cert resolver
- Added security headers and rate limiting middlewares to dynamic.yml
- Added example templates for public-facing service configuration
