upload: require auth on /upload/:type; bump sharp past libvips CVEs (S7)

POST /upload/:type fed the raw uploaded image straight into sharp with
no auth preValidation (unlike neighboring routes), reaching a native
libvips decoder in the container that holds the JWT secret and CLN hot
wallet. Require auth, and bump sharp 0.33.5 -> 0.35.3 (out of the
vulnerable < 0.35.0 libvips range, GHSA-f88m-g3jw-g9cj et al.).
