Consistent display format for configuration values on the Mesh page

[ferhoyos]

What do you want to improve?

UI alignment of the configuration values on the Mesh page.

What is the current behavior?

Currently, different configurations are displayed in different formats:

• YAML format for Istio config or Kiali status

• Table format for Kiali config and other components (Jaeger, Prometheus, Grafana, etc.)

What is the new behavior?

To avoid user confusion and improve UI alignment, all configurations should be displayed in the same format. The YAML format is the best approach because it is already familiar to users and better displays complex configurations (https://github.com/kiali/kiali/issues/7459).
