Maxscale GUI shows red ! when replication is working

A customer is running a 2-node Galera cluster in their Dev environment. Each node has an async replica that is not running Galera.

In 25.01.3, the Max GUI shows all four servers as healthy whether using galeramon or mariadbmon.

In 25.10.4, when using galeramon, the replicas show a status of `Read` in red with an exclamation mark next to them, even though replication is working. If the customer switches to mariadbmon, two of the servers show a status of `Up` with a red exclamation mark.

This behavior does not seem to affect query routing in either version (queries are routed appropriately, etc). It only seems to affect the visual representation in the GUI, and gives the impression that replication is broken even when it is working.
