The trusted-registry allowlist in api/rpc/package/config.rs splits the
image on '/' and matches the first segment against a fixed set (docker.io,
ghcr.io, git.tx1138.com, 23.182.128.160:3000, ghcr.io, localhost). A bare
'bitcoin/bitcoin:28.4' splits to registry="bitcoin" which isn't on the
list, so the install RPC was returning 'Invalid Docker image format'.
Live catalogs on .160 and gitea-local already hotfixed directly; these
static copies keep ISO builds and the final hardcoded fallback in sync.
