Add documentation and flow fix for duplicate quarantine notification emails

[Copilot]

Users receiving hundreds of duplicate "app released from quarantine" emails. Root cause: Dataverse webhook triggers on record updates even when admin_appisquarantined value unchanged. Daily sync flow updates all app records, firing notification flow repeatedly.

Changes

Flow modification

• Added admin_quarantineappdate to AdminSetappquarantinestatus flow select statement
• Enables deduplication logic implementation by users

// Before
"$select": "admin_displayname, admin_appdeleted, admin_appisquarantined"

// After  
"$select": "admin_displayname, admin_appdeleted, admin_appisquarantined, admin_quarantineappdate"

Documentation

• QUARANTINE-EMAIL-FIX-README.md: Entry point with 4 solution approaches (immediate workaround, deduplication logic, sync optimization, batch notifications)
• TROUBLESHOOTING-QUARANTINE-EMAILS.md: Root cause analysis, 5 solution patterns with trade-offs
• FIX-QUARANTINE-EMAIL-FLOW.md: Step-by-step implementation for recommended fix (add admin_lastquarantinenotificationdate field + conditional logic)
• ISSUE-RESPONSE-QUARANTINE-EMAILS.md: Technical details for maintainers
• GITHUB-ISSUE-RESPONSE.md: User-facing response template

Recommended implementation

Add tracking field to prevent notifications within 24h:

1. Create admin_lastquarantinenotificationdate column on admin_app table
2. Add condition before email send: check if notification sent today
3. Update tracking field after sending

Alternative simpler fix: Check if admin_quarantineappdate was set/cleared within last 24h before sending notification.

Comments on the Issue (you are @copilot in this section)

@harini-2-y Hi @nico-0823 , Thank you for bringing this to our attention. The emails you are receiving are compliance notifications indicating that your app’s status has changed from Quarantined to Released. These notifications are designed to inform app owners that the app is available for use again.

1. Identify the Triggering Flow
   Go to your CoE Starter Kit environment.
   Check for flows related to "Quarantine" (e.g., Admin | Quarantine and Review).
   Examine run history for flows that send notifications about quarantine release.
2. Review Flow Logic
   Look for repeated triggers or loops in the flow: Is the same app being flagged and released multiple times?
   Ensure that the logic properly marks apps as "reviewed" or "released" so notifications are not sent repeatedly.
3. Notification Settings
   Check notification actions (e.g., "Send Email" steps).
   Verify recipients—ideally, only app owners or specific admins should get these emails.
   Consider adding a condition to prevent duplicate notifications within a defined period.
4. Reduce Notification Frequency
   Implement throttling or batching in the flow: Send a daily summary instead of individual emails.
   Use Power Automate’s "Delay" or "Do Until" actions to avoid rapid-fire notifications.
5. App/Flow Mapping
   Use the CoE inventory tables (Apps, Flows) to identify which objects are being quarantined/released.
   If you don’t have inventory set up, consider enabling it for better tracking
