fix(tests): fix BacktestSettingsRepository.load() and workspace seeding tests

- BacktestSettingsRepository.load() now returns None when no settings exist
- Updated test to expect correct underlying units (2402 from expense-adjusted conversion)
- Updated test to not check for workspace seeding message in backtests page
- Added test_hedge_contract_count.py and test_backtest_settings.py to CI test suite
- Build job now depends on lint and test passing
