MQ Web Console - show full list of cluster queue managers and identify suspended ones

Use case / problem
We run IBM MQ 9.4 on OpenShift containers with the MQ Web Console enabled. From Manage -> Queue Manager -> MQ Network the console tells us a cluster's name, total queue manager count, suspended count, and health summary - but it does not list which queue managers are members of the cluster, nor which specific QM(s) are in a suspended state. To answer those two basic operational questions we have to drop into the queue manager pod and run DISPLAY CLUSQMGR(*) via runmqsc, which defeats the purpose of having a web console for cluster operations and observability.

Current behaviour
- Cluster summary shows: cluster name, member count, suspended count, health badge.
- No way to expand the cluster card to view the participating queue managers.
- No way to identify which queue manager(s) are suspended (only a count).

Proposed enhancement
1. In the cluster panel, allow drill-down to a list of cluster queue managers (equivalent to DISPLAY CLUSQMGR(*)) showing name, QMID, channel name, channel state, suspended status, full repository flag, and last-seen timestamp.
2. Surface a clear indicator (icon/badge) against any cluster QM that is suspended (SUSPEND QMGR CLUSTER(...)), so operators can immediately identify which member needs attention.
3. Optionally allow filtering/sorting by suspended state, channel state, or full-repo role.

Value
- Removes the need for SRE/operators to exec into QM pods just to inventory a cluster or find a suspended member.
- Brings the Web Console to parity with the operational visibility that runmqsc already provides.
- Improves incident response time (suspended QMs are a common root cause investigation).
- Aligns with the container/Kubernetes operating model where direct pod access is increasingly restricted.
