Description of Problem

• As identified by Gerald on Slack (https://redhat-internal.slack.com/archives/C01RQH8KQ87/p1758124742999619), if you name ArgoCD CR a different name than 'argocd' (for example you create ArgoCD CR with name 'openshift-gitops'), the operator will still use the redis address 'argocd-redis:6379' (and principal will look for a redis endpoint at that address).
• This value appears to come from `getPrincipalRedisServerAddress`

Acceptance Criteria

• The redis address used for principal should always point to the correct argocd redis Service in the namesapce.
  • So, for example, if the name of the redis service is my-argocd-redis, that is what the principal should point to.
• Unit/E2E test update to verify
