deploy.sh now checks local vs remote templates via md5sum on every
deploy and warns about drift. Pass --sync-templates to push changed
files. Also reports cached card image counts on the target server.
New clear-card-cache.sh script inspects or clears cached PNG/APNG
card images inside the API container, with --apng-only and --all
modes. Added scripts/README.md documenting all operational scripts.
