jgrusewski 845e77a8b0 fix(ci): Fix GitLab CI YAML syntax and PPOConfig compilation errors

Two critical fixes for successful pipeline execution:

1. GitLab CI YAML Syntax Fix (.gitlab-ci.yml:84-86)
   - Wrapped echo commands containing colons in single quotes
   - Root cause: YAML parser interprets `"text: value"` as key-value pairs
   - Solution: Single quotes force literal string interpretation
   - Impact: Enables Docker build pipeline execution

2. Trading Service Compilation Fix (trading_service/src/services/enhanced_ml.rs:1328-1348)
   - Added missing early stopping fields to PPOConfig initialization
   - Fields: early_stopping_enabled, early_stopping_patience, early_stopping_min_delta, early_stopping_min_epochs
   - Values: Disabled by default for paper trading (early_stopping_enabled: false)
   - Impact: Resolves pre-push hook compilation error

Technical Details:
- YAML Issue: Colons followed by spaces trigger mapping syntax parsing
- Single quotes preserve shell variable expansion while forcing literal YAML strings
- Early stopping config matches PPOConfig struct updates from Wave D
- Default values: patience=5, min_delta=0.001, min_epochs=10

Validated:
- ✅ YAML syntax validated with PyYAML
- ✅ trading_service compilation successful (cargo check)
- ✅ Ready for GitLab CI/CD pipeline execution

================================================================================ FINAL INTEGRATION VALIDATION REPORT

Date: 2025-10-30 Phase: Hyperopt Early Stopping Implementation & System Integration Status: PRODUCTION READY ✅

================================================================================

BUILD STATUS ================================================================================

✅ CLEAN BUILD (0 errors)

Command: cargo build --workspace --lib --bins --release
Duration: 4m 40s
Result: SUCCESS

Warnings (non-critical):
