User authentication to MyCalendar

[Nivyasudeesh]

Currently, MyCalendar does not have user authentication. There is no way for users to create accounts, log in, or log out.

Proposed feature:

• Add Signup button to allow new users to create accounts.
• Add Login button for existing users to access their accounts.
• Add Logout button for users to securely exit their session.

Benefits:

• Enables personalized calendar experience for each user.
• Improves security and data privacy.
• Allows features like saving events, reminders, and user-specific settings.

I would like to work on implementing this feature. Please assign this issue to me.
