### Apache Airflow version main (development) ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? In the [Airflow UI](https://github.com/apache/airflow/tree/main/airflow-core/src/airflow/ui) lacks some important accessibility features such as a proper lang attribute on the <html> tag and semantic navigation landmarks with appropriate ARIA labels. Additionally, iframe sandbox permissions are not explicitly defined to balance security and functionality. These missing details reduce usability for screen reader users and create potential security ambiguities. ### What you think should happen instead? In [ui](https://github.com/apache/airflow/tree/main/airflow-core/src/airflow/ui) is missing some important accessibility and security features: - In [2nd Line](https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/ui/index.html) - The root HTML element (`<html>`) does **not** have a `lang` attribute, which is essential for screen readers to correctly interpret the language of the page. - In [129th Line attribute of VStack](https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/ui/src/layouts/Nav/Nav.tsx) - The main navigation component (`Nav.tsx`) is missing semantic HTML usage (`<nav>` element) and a descriptive ARIA label (`aria-label`), reducing accessibility for users relying on assistive technologies. - In [15th Line](https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/ui/src/pages/Iframe.tsx) - The iframe component (`Iframe.tsx`) uses a sandbox attribute that only allows `allow-forms`, but it should explicitly include `allow-scripts` to enable necessary functionality while maintaining security controls. These omissions impact accessibility compliance (WCAG 2.1) and can cause usability issues for users relying on screen readers and can lead to potential iframe security misconfigurations. ### How to reproduce The following changes should be made: - **Add a `lang="en"` attribute** to the…
