Corrected access control and added conditional middleware.

Previous behavior

Highlighted in Issue #61 that allows unfiltered access to protected pages.

Changes Made

Reordered Middleware:

• Moved app.use(express.static('public')); below the other app.use statements to ensure proper handling of access control.

Added Conditional Middleware:

• Introduced a conditional middleware to exclude certain routes from token validation.
• Defined an array excludedRoutes containing routes that do not require token validation: ['/', '/register', '', '/login'].
• Implemented a middleware function to check if the request path is in excludedRoutes. If it is, the request proceeds without token validation. Otherwise, validateToken middleware is invoked.

Still had some routes missing. Will open a fresh pull with the other auth corrections.
