Enhance ComboHandler and orchestrator functionality with access control and error handling improvements

- Added AccessControl to ComboHandler for role-based access management. - Implemented gas estimation for plan execution and improved gas limit checks. - Updated execution and preparation methods to enforce step count limits and role restrictions. - Enhanced error handling in orchestrator API endpoints with AppError for better validation feedback. - Integrated request timeout middleware for improved request management. - Updated Swagger documentation to reflect new API structure and parameters.
