* test: reduce test_trading.py duplication with parametrize

Collapse repetitive individual tests in test_trading.py into
parametrized equivalents, cutting 267 lines without losing any cases.

- TestExtractTickPrice: 13 tests → 2 parametrized (×3 valid, ×10 None)
- TestEstimateOrderMargin: 4 invalid-margin tests → 1 parametrized ×4;
  nan/inf volume tests → 1 parametrized ×2
- TestNormalizeOrderVolume: multi-assert bodies split into parametrized
  cases for non-finite volume and constraints
- TestVolumeAndExecution: 9 place_market_order retcode tests → 1 ×11;
  5 update_sltp retcode tests → 1 ×5
- test_calculate_trailing_stop_updates_missing_symbol_digits:
  inline double-assert body → 1 parametrized ×2
