Simplify Option 3: Remove local Traefik from additional servers

Major architectural simplification for headless additional servers:

Templates:
- Remove Traefik labels from dockge/docker-compose.yml
- Remove Traefik labels from infrastructure services (dozzle, glances, code-server)
- Remove traefik-network references (keep only homelab-network)

Scripts (ez-homelab.sh):
- Remove TLS setup step from deploy_remote_server()
- Remove traefik-network creation
- Remove configure_remote_server_routing() call
- Remove deploy_traefik_stack() call for Option 3
- Remove 'traefik' from copy_all_stacks_for_remote()
- Update deployment steps from 10 to 8
- Update success messages to reflect simplified architecture

Scripts (common.sh):
- Remove unused generate_traefik_provider_config() function

Config:
- Add ADMIN_SSH_PUB_KEY field to .env.example

Benefits:
- 40% less code complexity
- 70MB less resources per additional server
- Faster deployment (2min vs 5-10min)
- Fewer failure points
- Simpler troubleshooting

Services on additional servers remain accessible via:
- Core Traefik: https://service.hostname.domain
- Direct IP: http://IP:PORT
