fix(traefik): update local dev ports and gitea SSH IP

- Change Traefik local HTTP port from 8080 to 8081 (conflict with cadvisor)
- Change Traefik dashboard port to 8093 (conflicts with cadvisor, Hyperion)
- Update Gitea SSH service IP from 172.23.0.2 to 172.23.0.3
- Note: Gitea SSH works directly via Docker port mapping in local dev
- Traefik TCP routing only needed for production (host network mode)
