Use separate read-only and read/write Docker Hub connections for private-fork pulls and upstream image publishing, removing the workflow dependency on a long-lived Docker Hub token.

Compare
Use the read/write OIDC connection in both repositories because the shared workflow publishes Docker Hub images from each.
Use the OIDC-capable action version consistently and rely on the login action itself to report missing connection configuration.
Mint short-lived package-write tokens for container publishing and remove package access from the built-in workflow token.
