Fix garage container command and drop postStart layout hook

The dxflrs/garage image ships as a single static binary with no
ENTRYPOINT and no shell, so `args: [server]` alone was exec'd as the
command (crash loop) and the shell-based postStart layout-bootstrap
hook could never run. Set command: [/garage] explicitly, and replace
the automated hook with documented one-time `kubectl exec` steps.

-On first install, the pod's postStart hook assigns and applies a single-node
-layout automatically. Check with:
-  kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage status
+REQUIRED one-time setup (Garage does not accept S3/admin traffic until a
+layout is assigned and applied):
 
-Create a bucket and access key with:
+  kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage status
+  NODE_ID=$(kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage node id -q | cut -d@ -f1)

+  kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage layout apply --version 1
+
+Then create a bucket and access key:
   kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage bucket create my-bucket
   kubectl -n {{ .Release.Namespace }} exec deploy/{{ include "garage.fullname" . }} -- /garage key create my-key
