Validate forms on login and registration pages

[Eduardoespl]

REQUIREMENTS / DESCRIPTION

As a user of the application, I want the forms on the login and registration pages to be properly validated to ensure accurate data entry and prevent errors during the authentication and account creation processes.

Goal:

The main goal of this issue is to implement form validation on the login and registration pages in order to provide a seamless user experience and minimize the occurrence of input errors.

Tasks

Beta Give feedback

1. Validate the name/email and password fields on the login and register form to ensure they are not empty.
2. Implement validation logic to verify that the entered username/email and password meet the required criteria (e.g., minimum length, allowed characters).
3. Display appropriate error messages near the invalid fields to provide feedback to the user.
4. Disable the buttons until all required fields are filled correctly.
