feat: Complete business logic implementation for Sage integration

- Implement all required business functions with proper error handling
- Add database operations placeholders (to be implemented with sqlor-database-module)
- Add HTTP client for remote Hermes service communication
- Provide complete API for Sage system to implement web endpoints
- Export all public functions via __all__

 """
-hermes-web-cli module - Business logic for Hermes multi-service management.
+hermes-web-cli module - Complete business logic implementation.
 
-This module provides the core functionality for managing multiple Hermes Service instances.
-It includes database operations, HTTP client for remote services, and utility functions.
+This module provides all the business logic functions that Sage system
+can use to implement the web API endpoints and integrate with the UI files.
 
-The module follows the standard Hermes module development specification:
-- Database tables: hermes_services, hermes_service_sessions
-- CRUD operations defined in json/ directory
-- Static files in wwwroot/ directory (automatically served)
+The .ui files in wwwroot/ contain static JSON configurations that reference
+API endpoints like "/api/hermes-web-cli/services". Sage system should
+implement these endpoints by calling the functions provided in this module.
