feat: integrate rate limiting and enhance security features

- Added @convex-dev/rate-limiter dependency to manage request limits effectively.
- Implemented rate limiting configurations for IPs, users, and endpoints to prevent abuse and enhance security.
- Introduced new security analysis endpoint to detect potential attacks based on incoming requests.
- Updated backend schema to include rate limit configurations and various cyber attack types for improved incident tracking.
- Enhanced existing security functions to incorporate rate limiting checks, ensuring robust protection against brute force and other attacks.
