Download badge and boss sprite images locally during export

The seed export command now downloads badge images and boss sprites
from remote URLs and stores them in frontend/public/, rewriting the
JSON URLs to local paths. Sprites are namespaced by game version
(e.g. /boss-sprites/red/brock.png) so each generation can have
its own sprite style.

 Badge images are currently loaded via remote URLs, which can lead to missing images if the remote source is unavailable. Download all badge images and store them locally as part of the seed script's export function.
