Migrate daily-ci to PAT-less Maven auth via MavenAuthenticate@0

Replace the ARTIFACTS_PAT-based settings.xml server with the MavenAuthenticate@0 task, which injects the build identity's OAuth token (System.AccessToken) into ~/.m2/settings.xml. The mirror is now mirrorOf=* with id matching the generated server id (feed name), so the single token-backed server authenticates all feed traffic under network isolation.
