Pull request overview

This PR adds an initial Axum-based server interface generator (generate.std-http-server) to oapi-codegen-rust, expanding the pipeline to lower OpenAPI paths/operations into a new server IR and then emit an axum router + trait-based handler contract. It also updates tests and documentation to cover and validate the new generator output.

Changes:

• Add server-path lowering (paths.rs) and IR types (Service/Operation/etc.) to generate an Axum Api trait, response enums, router, and handlers.
• Extend emit layer to render both models and server interface, and update CLI/lib entrypoints to generate based on config.
• Rename/refresh “golden” workflow to “generated” outputs and add fixtures/tests for supported + deliberately-unsupported server features.
