Build me a full stack CRM web app for a small sales team.

I want a secure login system with role based access for Admin, Manager, and Sales Executive, plus account lockout after too many failed logins. After sign in, users should land on a dashboard with key numbers and a few charts for leads, pipeline stages, and monthly sales.

The app should let users manage customers, leads, opportunities, follow ups, and activity notes with create, edit, delete, search, filtering, sorting, and pagination where it makes sense. Opportunities should track amount, probability, stage, expected close date, and show weighted pipeline value. Sales people should only see the records assigned to them, while managers and admins can see more.

Also include user management, audit logs, and basic reports. Make it clean and responsive, and use a modern React frontend with an Express and MongoDB backend. If you need current docs for any library, look them up online.
