The Image extension was configured with `inline: true`, but Docmost's
actual editor defines images as block-level nodes (`inline: false,
group: "block"`). This mismatch caused `update_page` to silently drop
all image nodes during the Yjs merge, since inline image nodes inside
paragraphs don't match Docmost's expected block-level image schema.
