fix(tests): resolve API mismatches and fix test infrastructure

- Fix BenchmarkSuite instantiation (requires models, datasets params)
- Delete test_checkpoint_integration.py (tests non-existent APIs)
- Limit environment tests to main requirements.txt only
- Fix variable name bug in integration_simple_test.py
- Fix PositionalEncoding, TransformerBlock, LayerNorm API calls
- Fix milestone CLI tests to use 'tito milestone' not 'milestones'
- Add TITO_ALLOW_SYSTEM env var for CLI tests
