fix: correct integration test to use ServerID instead of VersionID

The integration test in findServerIDByName was incorrectly returning
server.Meta.Official.VersionID instead of server.Meta.Official.ServerID,
causing 404 errors when verifying published servers. This fix ensures
consistent ID usage throughout the integration test flow.
