feat: room apis added

[ADARSHsri2004]

Description

Implemented backend APIs for video chat rooms. Authenticated users can now create, list, join, and leave rooms. JWT-based authentication protects all routes, and input validation ensures correct data handling. Proper error responses are returned for unauthorized access, invalid input, or not found resources. MongoDB schemas for rooms and user-room relationships are included.
