ci: verify call order of action-script hooks

The existing test collects all action-script hooks triggered during
`h`, `ns`, and `uns` runs with ZDTM into `actions_called.txt`, then
verifies that each hook appears at least once. However, the test does
not verify that hooks are invoked *exactly once* or in *correct order*.

This change updates the test to run ZDTM only with ns flavour as this
seems to cover all action-script hooks, and checks that all hooks are
called correctly.
