fix(kanidm): prevent ArgoCD from overwriting repl-cert ConfigMap data

Remove the data keys from kanidm-repl-certs in git so ArgoCD never takes
SSA ownership of them. Add ignoreDifferences for /data on that ConfigMap
in the ApplicationSet template so ArgoCD doesn't flag sidecar-patched
cert values as out-of-sync.
