feat: Implement audit logging and rate limiting middleware with SurrealDB integration
- Added audit logging middleware to track admin actions and save logs to SurrealDB. - Introduced rate limiting middleware for public endpoints and authentication endpoints. - Enhanced security headers middleware with nonce generation for CSP in development. - Created utility functions for extracting real client IP addresses from headers. - Updated Cargo.toml and Cargo.lock to include new dependencies. - Added new schemas for audit logs and rate limiting in the entities module. - Refactored permissions middleware to support new permission checks.
