Adds the docs-site page and the website marketing copy for the PDF
Viewer widget shipped in Pro 20260908.1.
- docs: full widget guide (source, zoom, toolbar, styling, gotchas),
listed in the Pro getting-started widget index, with the usual two
placeholder screenshots to be replaced with real captures.
- getting-started: PDF Viewer noted as having no WooCommerce or ACF
dependency.
- marketing: widget page plus a "What's included" entry and an updated
strapline on the Pro overview.

Drop the redundant documentation/marketing/ nesting inherited from the
plugin repos, so files sit at marketing/<plugin>/<page>.md. These paths
become raw URLs pasted into Elementor pages and ACF fields, so they are
much cheaper to change now than once sites reference them.
Fixes the four cross-plugin links for their new depth, and corrects the
README, which still pointed at the abandoned per-repo documentation/
folders instead of this repo.
