Pull request overview

This PR adds new home-data test fixtures for additional Roborock device/product variants (Saros 10 / model a147 and PearlS Lite / model a123) and expands snapshot-based testing to assert decoded DeviceFeatures across all available testdata device/product pairs.

Changes:

• Added new home_data_product_*.json and home_data_device_*.json fixtures for Saros 10 (a147) and PearlS Lite (a123).
• Extended tests/mock_data.py to build DEVICE_PRODUCT_PAIRS by joining device fixtures to product fixtures via productId.
• Added a parametrized snapshot test that constructs DeviceFeatures from home-data feature flags for every fixture pair, and updated snapshot outputs.

PTAL. Some of the fields changed. I think we may be missing app init status so this may be a little lossy compared to the past so we need to start storing that.
