[Feature]: Authentication Page ( Sign Up )

Is your feature request related to a problem? Please describe.

At the moment, the project does not have a dedicated signup page.

Describe the solution you'd like

• Design and implement a responsive signup page, ensuring it integrates seamlessly with the existing layout used for the left content.
• Ensure the page adapts to both light and dark themes, maintaining a visually appealing design when toggling between themes.
• Include loading states for the buttons and validation states for the input fields to enhance user experience and feedback.

Describe alternatives you've considered

I have considered using existing components from other authentication pages, but a dedicated, customized signup page will provide better control and a tailored user experience.
