traefik standalone adoption kit: live config versioned + compose + komodo panel router

- traefik.yml/dynamic/* copied from /etc/dokploy/traefik (acme.json gitignored — stays on host)
- compose.yaml: same image/binds/ports as dokploy-traefik, joins dokploy-network + komodo
- dynamic/komodo.yml: komodo.paginica.com router (inactive until cutover)

+# Standalone Traefik — adopción del traefik que hoy maneja Dokploy.
+# Misma imagen, mismos binds, mismos puertos. Desplegar SOLO al cortar:
+#   1. docker stop dokploy-traefik
+#   2. docker compose -f compose.yaml up -d   (desde este repo, o vía Komodo stack)
+# La config vive en /etc/dokploy/traefik (binds idénticos → cero churn de
+# acme.json/certs). Post-decommission de Dokploy se puede mover a /etc/traefik
+# (acme.json se copia con perms 600, nunca entra a git).
