fix(chaos): resolve compilation errors in chaos framework

Fixed API mismatches between chaos framework and monitoring package that were causing CI build failures:

**Type Corrections:**
- SystemThresholds → ResourceThresholds with correct field names
- AlertManagerConfig → MonitoringConfig unified configuration
- ResourceMonitorConfig → MonitoringConfig with proper structure

**Method Signature Fixes:**
- Fixed NewResourceMonitor() call to match actual signature
- Updated ResourceMonitor.Stop() call (no parameters required)
- Fixed StateChanges field usage (→ StateChangedAt)
- Replaced GetStats() with GetHealthStatus()/GetCurrentMetrics()

**Import Fixes:**
- Added missing resilience package import in chaos_test.go

**Validation:**
✅ go build -tags=integration ./tests/chaos/ - compiles successfully
✅ go vet -tags=integration ./tests/chaos/ - no warnings
✅ make build - regular build still works

These fixes resolve the underlying compilation errors that were preventing the chaos engineering integration tests from building, addressing the root cause of CI build failures identified in PR review comments.
