/**
* TrusteeAnalyseView
*
* Tab-based analysis page. Each tab maps to a bootstrapped template workflow
* (created from TEMPLATE_WORKFLOWS when the feature instance was set up).
* The workflow is loaded from the instance, executed via the workflow engine,
* and results/status are shown inline with polling.
