Fastapi-inertia

- Handle better JSONification of Pydantic models
- Use `json.loads(model.model_dump.json())` rather than `model.model_dump()`
To avoid issues with some common field types (UUID, datetime, etc.)
- Expose a `_render_json` method on inertia to allow easier overriding.

- Bump FastAPI version from 0.110.2 to 0.111.0
