Refactored IT: dcnm_network: SANITY and DELETED
Used Pydantic schema and DeepDiff for comparing expected data with ndfc data in the tests.

@neiljohn-gh Thanks for opening the PR! There are some CI errors that need to be resolved (https://github.com/CiscoDevNet/ansible-dcnm/actions/runs/15182282603/job/42694308666?pr=418). Let me know if you have any questions about them.

Back from CL and was giving this another review and running the various tests. Looks like there is an issue with the tests/dcnm/merged.yaml test.
