Support OpenAPI Specification

We need to implement OpenAPI support in the ebrick framework to standardize API documentation and provide integration for client-side tools and services.

Requirements:

1. Provide OpenAPI documentation for all exposed endpoints.
2. Use the OpenAPI 3.0 (or higher) specification.
3. Automatically generate OpenAPI documentation from route definitions and models.
4. Ensure real-time sync between API changes and documentation.
5. Support interactive API documentation via tools such as Swagger UI or ReDoc.

Some aspects need consideration:

1. Whether to enable API docs generation for any specific module or all modules.
2. Whether to generate API docs on the application booting-up phase or run a specific command line to trigger.
3. Whether to automatically generate API docs by source code analysis or using Gin Swagger and Swaggo with user manually inputted General API Info Comment
