Pull Request Overview

This refactor addresses two deprecation warnings: removes a deprecated custom event_loop pytest fixture and renames a dict field that was shadowing Python's built-in dict type. The changes maintain test functionality while eliminating warning messages.

• Removed deprecated custom event_loop fixture from conftest.py
• Renamed dict field to dict_field in EmbeddedJsonModelWithDict test model
• Updated all references to use the new field name
