wasm: fix workspace clippy — PdfPage::from_cells absorbs the ml image field

The workspace-wide clippy job unifies features: docling-cli enables
docling-pdf/ml alongside docling-wasm, so PdfPage grows its ml-gated
`image` field and docling-wasm's struct literal stopped compiling
(E0063). A cfg-aware constructor (from_cells, under ocr-prep) spells
the field only when it exists; the browser pipeline builds its pages
through it. Verified with the CI command verbatim
(cargo clippy --workspace --all-targets -- -D warnings) plus the
wasm32 target check.
