Add DLP troubleshooting guide for AppForbidden errors in CoE Admin Command Center

[Copilot]

Users encountering AppForbidden errors when opening the Flows section in CoE Admin Command Center lack actionable troubleshooting steps. The error occurs when DLP policies place required connectors (Dataverse, Power Automate Management, Logic flows) in different policy groups.

Changes

• New troubleshooting guide (docs/TROUBLESHOOTING-DLP-APPFORBIDDEN.md)

  • Root cause analysis: DLP policy connector group misalignment
  • 4-step resolution process with admin center navigation
  • Connector requirements matrix for all CoE components
  • Common scenarios: policy changes not applying, blocked connectors, multiple conflicting policies
  • Verification tests for Flows, Apps, Environment Variables, Setup Wizard

• Cross-references added to 5 existing docs

  • Core Components README: new "App Issues" section
  • TROUBLESHOOTING-UPGRADES.md: AppForbidden quick fix
  • docs/README.md, docs/troubleshooting/README.md: guide listings
  • docs/issue-response-templates.md: reusable response template

Connector Dependencies Documented

Microsoft Dataverse	Required	All CoE apps
Power Automate Management	Required	Admin Command Center (Flows)
