/**
* AR Aging PDF renderer — ar-aging-report (wave-12).
*
* Renders the report as HTML then converts via the HTML-to-PDF Worker pattern.
* RTL/Hebrew-aware: uses `dir="rtl"` when locale is 'he'.
* window.print() fallback documented below.
*
* NOTE: Cloudflare Browser Rendering is explicitly rejected per spec.
* The HTML-to-PDF Worker pattern encodes the HTML as base64, posts to a
* dedicated PDF-render Worker, and returns the PDF bytes. If the PDF Worker
* is unavailable, the route falls back to returning the raw HTML with
* Content-Type text/html and a `X-Print-Fallback: true` header so the
* client can trigger window.print().
