Preserve dict insertion order in safeformat output (fixes #13503)

[wak327]

This PR ensures that dictionaries in assertion output retain their insertion order, instead of displaying keys in alphabetical order. This matches Python 3.7+ dict behavior and improves debugging clarity for users.

• Updates safeformat to use sort_dicts=False with pprint.pformat.
• Adds a test to verify that dictionary keys are shown in insertion order in output.

Closes #13503.
