ci: add CLI management tests for target, LU, and TPGT commands

Add a new "CLI management test" step to the CI pipeline that exercises
the full lifecycle of the new management commands against a running
daemon:

- list target / list lu / list tpgt (read existing config)
- create target -> verify in list
- create lu -> verify in list
- rm lu -> verify removed
- rm target -> verify removed

Each step validates output with grep assertions so failures are
immediately visible.
