Duplicate similar addresses added to the Address List

Describe the bug
When adding addresses, the application allows similar or identical addresses to be added to the Address List multiple times, resulting in duplicates.

To Reproduce

Open Hamburger Menu.
Click on 'My Addresses'.
Click on 'Add New Address'
Add new address (e.g., "123 Main Street, New York").
Attempt to add the same or a similar address (e.g., "123 Main St., NY").
Observe the duplicate entry in the Address List.
Expected behavior
The application should prevent similar or identical addresses from being added to the Address List more than once.

Actual Result:
The Address List allows duplicate entries for similar or identical addresses.
