need to adjust multus unit sylvactl timeout
I observed a run where sylvactl watch timed out on `multus` unit.
The scenario was:
* an upgrade (where the multus DaemonSet updates Pods one at a time)
* multus unit reconciled between 2026-03-02T20:01:14 and 2026-03-02T20:07:57, i.e. it took nearly 7 minutes to reconcile
```

In the above we see that it took approximately 1 minute per node.
We can revisit `multus` unit sylvactl timeout to be "1.5minute per node" to have some margin.
