Add technical analysis for SharePointFormApp derived owner management

[Copilot]

Issue requests CoE utility to manage owners for orphaned SharePointFormApps—apps whose owners have left the organization. SharePointFormApp ownership cannot be changed via Power Platform APIs (product limitation). Issue consolidated into #10319.

Analysis Delivered

Created comprehensive feasibility assessment and implementation plan following existing Flow DerivedOwner pattern:

Technical Approach

• Add admin_DerivedOwner lookup field to admin_App entity (mirrors admin_Flow pattern)
• Update admin_setapppermissions app to include SharePointFormApps in orphaned list
• Add UI for derived owner assignment with clear scope messaging

Pattern Already Proven

// Existing Flow pattern (admin_setflowpermissions)
UpdateIf(Flows, Flow=SelectedFlow.Flow, 
  {DerivedOwner: LookUp(Makers, Maker=GUID(principal.id))});

// Proposed App pattern (same approach)
UpdateIf('PowerApps Apps', App=SelectedApp.App,
  {DerivedOwner: LookUp(Makers, Maker=GUID(principal.id))});

Key Constraints

DerivedOwner is CoE-specific governance field (reporting/tracking only). Does not change actual platform ownership—product limitation, not CoE limitation.

Documents Created

• docs/ENHANCEMENT_SUMMARY.md - Executive summary, effort estimate (16h), risk assessment (LOW)
• docs/orphaned-sharepointformapp-owner-management-analysis.md - 6-phase implementation plan, affected components, test cases
• docs/README.md - Documentation structure

Recommendation: Feasible, low-risk, follows proven pattern. Ready for implementation approval.

This section details on the original issue you should resolve

<issue_title>[CoE Starter Kit - Feature]: CoE utility to update Owner/Derived Owner for orphaned SharePointFormApps</issue_title>
<issue_description>### Is your feature request related to a problem? Please describe.

I am trying to clean-up orphaned SharePointFormApps, but there is no way to do it natively in the Power Platform administration or COE toolkit. All SharePoint form apps are managed through the Sharepoint interface. While another user can modify the app from SharePoint, the owner doesn't change. This creates an issue with the owner has left the organization and the SharePointFormApp is orphaned.

Describe the solution you'd like

A CoE toolkit utility that will let you update the Owner for a SharePointFormApp. The Power Platform flows utility has a similar feature to update a "derived owner", so at least the CoE toolkit reporting recognized a new owner.

Describe alternatives you've considered

Creating a custom flow that modifies the PowerApps App table to change the owner

Additional context?

I have noticed other users on the internet with similar issue. Here is a Reddit article describing such: https://www.reddit.com/r/PowerApps/comments/wwt2mb/change_owner_of_sharepointformapp_pa_in_spo_not/
