fix(cli): restore typer.Exit to exception handlers and step catch clauses

In this project typer.Exit is its own exception class distinct from
click.exceptions.Exit. A prior attempt narrowed the catch clauses in
actor.py and actor_run.py to click.exceptions.Exit only, and removed
typer.Exit from the step-function catch tuples in the resolve and
security step files. This caused two categories of CI failures:

- Scenarios 38 and 56 (FAIL): _not_found_resolve raises typer.Exit(code=2)
  inside the CLI command; without the catch in the run() handler it fell
  through to the generic except Exception branch and was re-raised as
  exit_code=3, failing the assertion exit_code == 2.

- Scenarios 74-100 (ERROR): resolve_config_files raises typer.Exit(code=2)
  directly; the step functions only caught (SystemExit, click.exceptions.Exit)
  so the exception escaped uncaught, causing Behave to report ERROR instead
  of a clean assertion result.

Fix: restore `except (click.exceptions.Exit, typer.Exit): raise` in both
CLI modules, and add typer.Exit back to every step-function catch tuple
that wraps a resolve_config_files call.
