[Python] Unit Tests for Client Wrapper (Mocks)

[realfishsam]

Purpose / Goal

The Python SDK is currently tested primarily via integration tests against the live sidecar. We need isolated unit tests for client.py to ensure the data conversion logic (_convert_market, etc.) is robust against API changes.

Tasks

• Create sdks/python/tests/test_converters.py.
• Use pytest and \unittest.mock` to simulate the sidecar server's JSON responses.
• Assert that the data models (UnifiedMarket, OrderBook) are correctly instantiated with the expected values.

Easy Way to Get Started

1. Create a sample JSON file representing a market from the Polymarket API.
2. In your test, pass this JSON to the _convert_market function in client.py.
3. Check if attributes like market.title and market.yes.price match the JSON source.
