Form Validation Improvement PR

Overview

This PR enhances form validation across the application by removing unnecessary validation checks that block form submissions, improving user experience by allowing users to attempt submissions even when validation errors are present.

Key Changes

Form Button Submission Logic

• Removed isValid checks from form submission buttons in multiple components, the submit button should not be disabled from pressing
• Server-side validation errors will still be properly displayed
• Form fields will still show individual validation errors to guide users

Error Handling Improvements

• Added proper Alert components to display server errors in authentication forms

Just one suuuuuuuper minor thing that's totally not a blocker.
