API - Get Current User Endpoint

[AMAN-BARBARIA]

Goal: Implement an API endpoint to retrieve the current authenticated user's details.

Background: Currently, we do not have a dedicated endpoint for fetching the details of the currently authenticated user. This endpoint is important for allowing the client to fetch user details after login or page refresh, etc.

Tasks:

• Design and implement a new API endpoint
• The endpoint should return the currently authenticated user's details.
• Ensure proper authentication checks are in place - only the logged-in user should be able to access their own details.
• Implement error handling to cover cases like unauthenticated access, server errors, etc.
• Write tests for the new endpoint
