fix(k3d): clean up prole-registry and fix registry running check

k3d-prole-registry was squatting on port 5000, leaving k3d-knoe-registry
in created state. Two bugs made this invisible:

- k3d_registry.py: substring match (name in stdout) matched k3d-knoe-registry
  as already-exists without checking STATUS=running; add _k3d_registry_running()
  requiring last column == running, detect and delete prole-registry before
  creating knoe-registry, recreate if found in non-running state
- status_common_services.sh: grep -qx 'knoe-registry' (exact) never matched
  k3d prefix 'k3d-knoe-registry'; fix with awk suffix match + STATUS==running
