Fix the poster URL helper's wrong extension, and correct a stale header

posterUrl() said .png. There are 378 poster .webp files and no matching .png, so
the helper could only ever have produced a 404 — but it was never called, because
the export and print paths each built the same URL inline. A dead helper carrying
a wrong constant is worse than no helper: it is primed to break whoever tidies up
by routing a call through it. Point it at .webp and route both callers through
it, so the format lives in one place.

The file header still said posters "DO NOT EXIST YET. Nothing has been generated."
378 previews are generated, shipped and served live, and the wall paints from
them. A reader following that line would go build a generator that already ran.
Replace it with what actually ships: previews by default, full-resolution posters
excluded because bundling them pushed the tree past what the catalog would accept.
