Adds two egress allows to monitoring-netpol so Prometheus can scrape
FlowerCore.RemoteDesktop:
1. fc-desktop namespace on port 8080 — direct ClusterIP service
target (remotedesktop-web.fc-desktop:8080).
2. traefik-system namespace pods on ports 8080 + 8443 — covers the
Traefik VIP hairpin path for the `https://desktop.iamworkin.lan`
scrape target (CoreDNS wildcard resolves iamworkin.lan hostnames
to the LB VIP; after kube-proxy DNAT, egress needs the backend
pod port allowed per feedback_netpol_dnat_backend_port).
Without these, the fc-remotedesktop scrape times out with "context
deadline exceeded" even though the monitoring-netpol already allows
the 10.0.56.0/24 CIDR — post-DNAT the destination is a 10.42.x.x
pod IP, not the VIP.
