refactor: migrate to Elysia and enhance security middleware
- Replaced Express with Elysia for improved performance and type safety - Integrated Elysia middleware for rate limiting, security headers, and request validation - Refactored security utilities to work with Elysia's context and request handling - Updated token management and validation logic - Added comprehensive security headers and input sanitization - Simplified server initialization and error handling - Updated documentation with new setup and configuration details
