feat(netbird): deploy the reverse-proxy-services controller

Deployment for the controller of the previous commit: openbao namespace
like the rotators (its default-deny already allows OpenBao, DNS, the
apiserver and world), own ServiceAccount with a read-only ClusterRole
(Ingresses list/watch, Services get), one replica, Recreate. The image tag
is the branch build that pushed this exact code.

The OpenBao role is applied once by hand (policies/netbird-proxy-services
.hcl); until then the pod logs an auth error per minute and changes nothing.
