Contact address update does not persist despite success message

Bug Description

When editing an existing contact's address, the system displays a success message indicating the changes were saved, but the address update does not actually persist to the database.

Steps to Reproduce

1. Navigate to Contacts page
2. Open an existing contact that has an address
3. Edit the address fields (e.g., change street, city, etc.)
4. Click Save
5. Observe success toast message appears
6. Refresh the page or re-open the contact

Expected Behavior

The updated address should be saved and visible after refresh.

Actual Behavior

The success message is shown, but the address reverts to its original values after refresh - the update was not persisted.

Impact

Users believe their address changes are saved when they are not, leading to data inconsistency and confusion.
