Add FSRS config key and disable FSRS in legacy scheduler tests

- Add FSRS boolean config key to protobuf definition
- Update generated Rust config mapping code
- Disable FSRS in test_schedv3.py tests to maintain legacy scheduler behavior
- These tests are designed for the old SM-2 algorithm, not FSRS
