closes: #61452 ## Summary This adds Helm chart support for exposing the **Webserver** with Kubernetes Gateway API `HTTPRoute` on the 1.2x chart line (Airflow 2.x). - adds `webserver.httpRoute` values, schema, template, tests, and docs; - routes the default backend to the Webserver service on `ports.airflowUI`; - supports custom labels, annotations, hostnames, `parentRefs`, path settings, and full `rules` override; - renders only for Airflow 2 (`airflowVersion` < 3.0.0), where the Webserver exists — on Airflow 3 the API Server replaces it; - fails fast when Webserver Ingress and Webserver HTTPRoute are both enabled (guarded from both the HTTPRoute and the Ingress template); - extracts the shared `httpRoute` schema into `definitions.httpRoute` so `apiServer`, `flower`, and `webserver` reference one definition instead of three near-identical copies. ## Validation E2E screenshot through the Gateway API path (Envoy Gateway, Airflow 2.11): <img width="1912" height="1036" alt="61452_webserver_httproute" src="https://github.com/user-attachments/assets/57f19694-6927-4128-93e5-3f81f6a0b017"; /> The port-forward targets the **Envoy Gateway dataplane service** and the URL host `airflow.localhost` is the Gateway listener hostname, so the request path is: ```text browser -> Envoy Gateway service -> Gateway listener -> Webserver HTTPRoute -> airflow-webserver service ``` --- ##### Was generative AI tooling used to co-author this PR? <!-- If generative AI tooling has been used in the process of authoring this PR, please change below checkbox to `[X]` followed by the name of the tool, uncomment the "Generated-by". --> - [x] Yes (please specify the tool below) Generated-by: [Claude Opus 4.8] following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) --- * Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
