examples: test_e2e.py reads non-existent ReplayResult.status / .id

[LukasPoque]

examples/livekit-voice-agent/driver/test_e2e.py (~lines 59, 62) accesses result.status and result.id on the ReplayResult returned by xray.run(...).

ReplayResult has no status or id field — its fields are replay_id, conversation_hash, passed, assertions, judges, metrics (sdk/python/src/xray/conversation.py). The current code raises AttributeError at runtime.

Fix: use result.replay_id and result.passed.
