Problem
Encrypted chat assets carry the original PDF but no first-page thumbnail, so the receiver cannot show a preview without downloading the document.
Solution
Asset.previewfield and preserve it through message mapping.e2e-pdf-previewbut keep it off by default in every build, including Edge, until the receiver UI lands. Explicit opt-in remains available.No backend, protocol-schema, or dependency changes. This PR adds no receiver preview UI.
