Added LOS column on Loans & Leads list

The primary purpose of this patch was to improve loan visibility by allowing loan officers to quickly verify whether a loan is synced to the LOS directly from the Loans & Leads list, without needing to open each loan individually. Loan officers previously had no direct way to identify LOS sync status from the Loans & Leads list and had to open each loan to check.
