[MM-63555] mmctl: Add compliance export show and cancel cmds (#30569)

* add compliance export cancel command and tests

- Introduced `ComplianceExportCancelCmd` to allow cancellation of compliance export jobs.
- Implemented unit tests for the cancellation command, covering successful cancellation, error handling for non-existent jobs, and cancellation in non-cancellable states.
- Added end-to-end tests to validate the command's functionality in the E2E test suite.

* mmctl docs

* clean up example text; remove unneeded getJob

* fix tests

* fix tests, again.

* prefer hyphen for command naming

* update docs
