Pull request overview
Adds a new Zero Trust assessment test (51013) under the PowerShell test suite to evaluate whether Intune App Protection Policies enforce a block/wipe action when managed apps cannot re-authenticate the user (e.g., disabled accounts, blocked sign-ins, revoked/expired tokens), and surfaces the configuration in the report output.
Changes:
- Introduces
Test-Assessment-51013to query iOS/Android managed app protection policies and evaluateappActionIfUnableToAuthenticateUser+ assignment state. - Generates a markdown report table summarizing the auth-failure action and whether each policy would pass/fail.
- Adds a matching
Test-Assessment.51013.mddescription/remediation doc that plugs intoAdd-ZtTestResultDetail.

Error handling does not distinguish 401/403
The spec says Investigate when Q1/Q2/Q3 returns 401 or 403. The implementation marks any Graph error as Investigate.
Let's check with @KalwaniRavi if that's OK.

Is the explicit cast to [int] necessary?
