[Feature]: Add Role based access control to running workflows - Implement updated endpoints in UI

[wouter1975]

In several places the update endpoints for running workflow/tasks need to updated in the FE.

• Reflect the isAllowed state in the Start menu
  • is workflow has isAllowed = false, make the menu item (shown by the product name) not-clickable, and present the item in a disabled state (grey text)
• Reflect the isAllowed state in the Tasks menu
  • is workflow has isAllowed = false, make the menu item not-clickable, and present the item in a disabled state (grey text)
• extend the isAllowed function on the Abort and Delete button to check whether the user is entitled to abort or delete the workflow
• Ensure that the resume step performs an isAllowed check before the new input is accepted and workflow continues into running state.
