Stop the CI from re-fetching crests, cache their URLs instead

Fetching 56 images on every run earned nothing but rate limits, and the
CI artefact is a test build that does not need the badges — the shield
fallback covers it. The resolved image URLs are cached in
tools/crest-sources.json, which is plain text and safe to commit, so a
local run needs one request per club instead of two and can resume after
a rate limit. The artwork itself stays out of the repository.
