♻️ Migra API pública de actix-web a Axum

- `configure_service` como `configure_router(Router) -> Router`.
- Macro `static_files_service!` como `serve_static_files!`.
- `ResultPage<M, E>` eliminado; handlers devuelven `Result<M, E>`.
- `ErrorPage` implementa `IntoResponse` en lugar de `ResponseError`.
- Registro con `OnceLock`; eliminados `drop_extensions` y `app.welcome`.
- `Redirect` devuelve `Response`; docs y ejemplos actualizados.
