🎯 Wave 25: Fix all 349 data crate test compilation errors

Browse Source 
Successfully resolved all test compilation issues across data crate:

**Major Fixes:**
- Fixed Price::new() signature changes (i64 → f64 parameter)
- Fixed Quantity::new() signature changes (returns Result)
- Added missing QuoteEvent fields (sequence, conditions as Vec)
- Fixed config struct field mismatches (RegimeDetectorConfig, TrainingFeatureEngineeringConfig)
- Fixed Result type alias conflicts with std::result::Result
- Added missing TimeInForce imports
- Fixed async test functions (added #[tokio::test] attribute)
- Fixed PortfolioAnalyzerConfig and RegimeDetectorConfig scope issues
- Updated Subscription creation (removed quotes() helper, use direct initialization)

**Files Modified (18 total):**
- data/src/brokers/interactive_brokers.rs: Fixed TimeInForce import, error types, docs
- data/src/features.rs: Fixed RegimeDetectorConfig test fields
- data/src/parquet_persistence.rs: Added base_path() getter, updated MarketDataEvent
- data/src/providers/benzinga/: Fixed NewsEvent field mappings, Result type alias
- data/src/providers/databento/: Fixed async tests, Price/Quantity signatures
- data/src/storage.rs: Added missing path and partition_by fields
- data/src/training_pipeline.rs: Added enable_log_returns/normalization/scaling fields
- data/src/types.rs: Fixed Subscription and QuoteEvent creation
- data/src/unified_feature_extractor.rs: Fixed config scope issues
- data/src/utils.rs: Fixed histogram percentile calculation, FIX parser tests
- data/src/validation.rs: Cleaned up documentation
- data/tests/parquet_persistence_tests.rs: Updated test code

**Results:**
- ✅ 349 errors → 0 errors (100% resolution)
- ⚠️ 474 warnings remain (will be addressed in Wave 26)
- ✅ Data crate tests now compile successfully
