Improve how Clarity deals with missing Dynamo scripts
Current situation if a script is not available on the task servers anymore:
- Can't create new tasks for this script (good)
- Existing tasks can be copied (not so good imo)
- In edit mode, the Dynamo inputs section is missing (of course)
- In edit mode, there is no indication as to what is going on with that task (definitely not good)
- If scheduled, the task is never claimed (not good either)
Suggestions for improvement:
- Show a warning in edit mode (e.g. "Dynamo script could not be found on any task server")
- If scheduled, have such tasks fail immediately
- Do not allow copying of such tasks
