fix(cli): exit with non-zero code when configure/agents-add wizards are cancelled (#14156)

* fix(cli): exit with non-zero code when configure/agents-add wizards are cancelled

Follow-up to the onboard cancel fix. The configure wizard and
agents add wizard also caught WizardCancelledError and exited with
code 0, which signals success to callers. Change to exit(1) for
consistency — user cancellation is not a successful completion.

This ensures scripts that chain these commands with set -e will
correctly stop when the user cancels.

* fix(cli): make wizard cancellations exit non-zero (#14156) (thanks @0xRaini)
