[skmo] Replace shell tasks with kubernetes.core in prepare-leaf

Address non-blocking review suggestions from evallesp and fultonj on
ci-framework PR #3766.

- Replace the 'Ensure leaf osp-secret exists' and 'Read leaf admin
  password' shell tasks with a single set_fact that parses the
  osp-secrets.env file directly using regex_findall. Pre-creating the
  secret in the leaf namespace is unnecessary because kustomize already
  creates it there during stage 6; the hook only ever needed the
  password value itself.
- Replace the 'Create TransportURL CR' and 'Wait for TransportURL'
  shell tasks with kubernetes.core.k8s (idempotent apply) and
  kubernetes.core.k8s_info with retries/until (condition polling).
