feat: Implement logging infrastructure and error handling

- Added tracing configuration with support for JSON and plain text formats
- Implemented request logging middleware to track HTTP requests and responses
- Created error handling middleware for consistent API error responses
- Updated main.rs to initialize logging and apply middleware
- Fixed RedisRateLimiter to implement Clone trait
- Updated plan-progress.md to mark logging tasks as completed
