[FEATURE] Enhanced User Feedback for Login Process

[chikatlarakesh]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I log in and the button doesn't provide feedback during the process. When incorrect credentials are entered, there's no clear error message indicating what went wrong, which can be confusing for users.

Describe the solution you'd like
I would like to implement a loading spinner on the login button to indicate that the login process is in progress. Additionally, if the login fails due to incorrect credentials, a clear error message should be displayed below the password input field to inform users about the issue.
