Add error handling for Get_App_Role_Assignments_as_Admin in SYNC HELPER - Apps

[Copilot]

SYNC HELPER - Apps fails when Get-AdminAppRoleAssignment API returns blank errors (deleted apps, permissions issues, throttling). Missing error handling causes entire flow failure.

Changes

Flow: SYNCHELPER-Apps-B677AA25-8DE4-ED11-A7C7-0022480813FF.json

• Added Handle_Failed_Role_Assignment action (Compose, returns []) with runAfter: Get_App_Role_Assignments_as_Admin → Failed | TimedOut
• Updated Filter_to_tenant:
  • runAfter: dual path (success + error handler skipped)
  • from: @coalesce(outputs('Get_App_Role_Assignments_as_Admin')?['body/value'], outputs('Handle_Failed_Role_Assignment'))

Pattern matches CLEANUP HELPER - PowerAppsUserSharedWith flow.

Flow behavior:

Get_App_Role_Assignments_as_Admin
├─ Success → Filter role assignments → Mark sharing status
└─ Failed  → Empty array → Continue (app marked as not shared with tenant)

Apps with failed API calls are inventoried with incomplete sharing data; next sync retries.
