* 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

* test: further reduce test_trading.py duplication with parametrize

Merge six broker stop-level tests into two parametrized tests, collapse
two default-digits fallback tests and three symbol-filter zero-margin
tests into one each.

* test: address claude[bot] review on PR #64

- Consolidate _MISSING_RETCODE sentinel to one line with corrected comment
- Add comment explaining ids list is required for deterministic node IDs
- Document intentional narrower retcode coverage in update_sltp test

* test: reduce duplication in test_sdk, test_history, test_contracts

- TestBuildConfigWholeDollarEnv: 3 field tests (server/password/path) → 1
  parametrized ×3
- TestResolveAccountSpec: whole-dollar expand/no-expand pair → 1 parametrized ×2
- test_normalize_mt5_exception_maps_types: 2 isinstance asserts → parametrized ×2
- test_resolve_history_tick_flags_invalid: 2 pytest.raises blocks → parametrized ×2
