Added Authentication with Bcrypt
Updated server/server.js:
Implemented user authentication with bcrypt for password hashing.
New users are registered with hashed passwords stored in the database (User model).
Existing users can log in; passwords are verified against the bcrypt hash.
Wrong password attempts send "ERROR: Wrong password" to the client and disconnect them.
Users are marked online when connected and offline when disconnected.
All user connections are logged in the database with connectedAt timestamp.
Updated server/models/User.js:
server/models/Message.js:
