🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Remove the CNI file before startup setup in both DaemonSets.

Both DaemonSets mount the host /etc/cni/net.d, and their probes only test 10-ovn-kubernetes.conf. ovnkube --init-node writes the file only if it does not already exist. If a restart bypasses preStop, the stale file can satisfy both probes while initialization continues. Remove the file as the first startup command, before setup commands and exec /usr/bin/ovnkube, in both DaemonSets.

In `@assets/components/ovn/multi-node/node/daemonset.yaml` at line 168, Update
both DaemonSets to remove /etc/cni/net.d/10-ovn-kubernetes.conf as the first
startup command, before any setup commands or exec /usr/bin/ovnkube, while
preserving the existing probe behavior.
