fix(ui): show container logs when using `templateRef`

[agilgur5]

Fixes #9938 Related to #12970 -- that's for the back-end, this is the one remaining place in the front-end

Motivation

• the component was incorrectly assuming that node.templateName exists, which it doesn't in the case of a templateRef

Modifications

• use the existing getTemplateNameFromNode function to properly handle that instead

Verification

Used the WorkflowTemplate and Workflow from the issue repro, can see all containers and logs.
