[ci skip] fix MySQL service: point at mysqld pods, pin to healthy primary

Browse source 
The InnoDB Cluster Router (mysqlrouter) doesn't deploy when the cluster
lacks quorum. Changed service selector from mysqlrouter to mysqld with
publishNotReadyAddresses=true to bypass the operator's readiness gate.
Pinned to mysql-cluster-1 (healthy primary) until full cluster recovers.
