fix: deduplicate missing-key warnings and normalize match_details

Addresses second round of PR #102 review:
- _warn_missing_key(): logs each missing key only once per engine instance
  to prevent log spam in high-frequency trading loops
- _build_match_details(): uses _safe_float() normalized values instead of
  raw market_data to ensure consistent float types in logging/analysis
- Test: verify warning fires exactly once across repeated calls
- Test: verify match_details contains normalized float values
