Refactor routing and proxy components for improved structure and compatibility

- Removed deprecated route utility functions in favor of direct matcher usage.
- Updated imports to reflect new module structure for routing utilities.
- Consolidated route manager functionality into SharedRouteManager for better consistency.
- Eliminated legacy routing methods and interfaces, streamlining the HttpProxy and associated components.
- Enhanced WebSocket and HTTP request handling to utilize the new unified HttpRouter.
- Updated route matching logic to leverage matcher classes for domain, path, and header checks.
- Cleaned up legacy compatibility code across various modules, ensuring a more maintainable codebase.
