Browse Source 
<UserStory> ADM003: Login </UserStory>

<Changes>
    1. Added credential input handling in UserInterface::login with username and password prompts.
    2. Integrated Controller::login to validate credentials and retrieve authenticated user.
    3. Implemented role-based menu navigation: Admin → AdminMenu, Technician → TechnicianMenu, Customer → CustomerMenu.
    4. Added error handling for invalid credentials and unknown user types with clear feedback messages.
    5. Included util::clear for screen refresh and structured output formatting during login.
</Changes>

<Test>

  Precondition:
  1. Valid user accounts exist in the system (Admin, Technician, Customer).
  2. Controller is connected to UserManagementService for authentication.
  3. UserInterface is initialized with role-specific menus.

  Steps:
  1. Launch UserInterface and select "Login".
  2. Enter incorrect username or password.
    - Verify that system displays "Error: Invalid Username or Password".
  3. Enter valid admin credentials.
    - Verify that AdminMenu is displayed successfully.
  4. Enter valid technician or customer credentials.
    - Verify that TechnicianMenu or CustomerMenu is displayed accordingly.
</Test>
