Add Remember Me Functionality to Registered User Login

[cvairlis]

Pull Request Description

This pull request introduces support for the "Remember Me" functionality during the registration process in the RegisteredUserController. The changes ensure that users are logged in with the remember parameter based on the form input provided during registration.

Changes Made

1. Added $request->boolean('remember') in the store method of RegisteredUserController to handle the "Remember Me" option.
2. Updated tests in RegisteredUserControllerTest:
   • Added a test to verify that the remember option works when set.
   • Added a test to confirm that the login defaults to not remembering the user when the option is not set.

Impact

• Enhances user experience by allowing users to stay logged in if they choose to do so during registration.
• Backward-compatible, with no breaking changes introduced.

Testing

• All existing tests pass.
• New tests added to ensure the "Remember Me" functionality behaves as expected in both scenarios (enabled and disabled).
