✨ Render thumbnails for graphers by uuid

[danyx23]

This PR duplicates the thumbnail rendering logic into the top level so that we can render pngs at /grapher/SLUG.png and svgs at /grapher/SLUG.svg. It also adds thumbnail rendering at /grapher/by-uuid/UUID.png and .svg.

The HTML rewriting (of og images) is changed to point to the new /grapher/SLUG.png route.

The old thumbnail rendering at /grapher/thumbnail/SLUG is kept for now so that existing fetches will still work until the various cached versions of the HTML have expired.
