- Add additional logging when the router starts to display the number of rules and their details, including names and specific configurations for APIProxy and SOAPProxy.
- Implement helper methods to format rule display names and custom names for better clarity in logs.
- Update `InternalProxy` initialization to use `StringUtils` for key generation.

Implement methods to format and group OpenAPI records by directory. Enhance the display output to include detailed location information when OpenAPI records are present.

- Create a new test class `OpenAPI31ReferencesTest` for validating OpenAPI 3.1 references.
- Implement setup method to initialize the router and load OpenAPI specs.
- Update test cases to handle requests for both `/pets` and `/users` endpoints.
