Share Feed User Visibility & Notifications

The primary purpose of this patch was to display the actual user who shares the 1003 or mobile app with borrowers or realtors, and to notify the Loan Officer when another user shares their 1003 or mobile app. This improves transparency, communication, and oversight of user activities.

• Added user identification in Share Feed for all 1003 and mobile app sharing activities
• Introduced real-time notifications for Loan Officers when another user shares their 1003 or mobile app
• Enhanced visibility into borrower and realtor engagement
• Improved accountability and tracking of shared actions across users
• Strengthened team collaboration and awareness with timely updates
• Minor UI enhancements for clearer and more intuitive activity display
