Create middleware to validate if user is part of Discord

[surajmaity1]

Issue Description

Create a middleware to check if the user is part of Discord or not.

Current Behavior

We are checking in every controller if the user is part of Discord. Ideally, there should be a middleware that performs this check before reaching the controller.

Expected Behavior

A middleware should be implemented to verify whether the user is part of Discord. If the user is not part of Discord, the middleware should return a 403 Forbidden response, preventing any further operations. This middleware can be reused across routes that require this validation. It can be integrated into relevant route handlers to ensure that only authorized users who are members of Discord can access the protected resources or perform specific actions.
