Validate native AppLocker EXE event generation with an opt-in probe (#423)

* Add native AppLocker EXE event validation probe

* Reference PR 423 in changelogs

* Isolate AppLocker native fixture and preserve prerequisite diagnostics

* Report an integer zero for an empty AppLocker policy

* Prepare disposable AppLocker probe policy without bypassing production importer guards

* Retain bounded native AppLocker channel diagnostics on probe failure

* Require native policy application before the disposable AppLocker probe

* Preserve exact timestamp strings in native evidence fixtures

* Record actual runner session and AppLocker publication diagnostics

* Activate and restore the native policy converter on disposable AppLocker hosts

* Compare native task freshness without guessing its timestamp timezone

* Verify effective policy and borrowed converter inactivity during fixture cleanup

* Track the actual native policy-converter task instance instead of cached timestamps
