Description of Problem

• As discussed on Slack (https://redhat-internal.slack.com/archives/C01RQH8KQ87/p1757693599834029), and see the linked Google doc, at present the NetworkPolicy created for Argo CD Redis via Argo CD Operator is missing some additional rules for the argo cd agent case.
• Since Argo CD agent must be able to connect to argo cd redis, for some essential functionality (such as redis proxy), it is necessary to have the redis NetworkPolicy allow traffic from Argo CD agent.

Acceptance Criteria

• When Argo CD agent is enabled via ArgoCD CR, the redis NetworkPolicy should allow traffic from argocd-agent to redis.
• As mentioned in Gerald's doc, we can either use a separate NetworkPolicy, or we can integrate these rules into existing (single) NetworkPolicy
• Unit/E2E tests to verify.
