Write PetriNet MIRA model edit tests in the integration dashboard

[liunelson]

As part of implementing PetriNet model editing in Terarium, we should:

• create a TA2 section in the integration board
  • https://github.com/DARPA-ASKEM/integration-dashboard
  • https://integration-dashboard.terarium.ai/TA3
• write some unit tests based on the model-edit code snippets
  • list of operations & code snippets: https://docs.google.com/document/d/1zzh-F7QKhvzwRibpBR0KkNxZ284EaU_DuDWWBsA_SrA/edit#heading=h.gex5uyr8umh9
  • ideas: https://github.com/gyorilab/mira/blob/main/tests/test_template.py

Does this task make sense to you?

Yep this makes sense to me. We could put those unit tests here or put them somewhere else. I don't have strong feeling either way; we don't really have a TA2 specific repo for this type of thing.
