test(integration): adjust t10 restore matrix run

[enyst]

This PR splits out the integration-test-only changes that were included in #1542.

Changes included:

• .github/workflows/integration-runner.yml: runs t10_restore_conversation once (restore config selected from the matrix)
• tests/integration/run_infer.py: only skips t10_restore_conversation when running in integration mode; reads restore config from the matrix
• tests/integration/tests/t10_restore_conversation.py: adds/updates the restore behavior test

Goal: keep #1542 focused on the reconciliation removal, while we iterate on integration test behavior without needing to run the full LLM matrix.

About Multi-Architecture Support

• Each variant tag (e.g., 0c49e4a-python) is a multi-arch manifest supporting both amd64 and arm64
• Docker automatically pulls the correct architecture for your platform
• Individual architecture tags (e.g., 0c49e4a-python-amd64) are also available if needed
