Issues Fixed in This Commit

1. Service Initialization: All services now properly initialized with required dataProvider parameter
2. Method Signatures: Fixed getSecurityMetrics() to use correct parameter format (3 separate params instead of object)
3. Type Safety: Fixed Industry type from "finance" to "financial"
4. Unused Variables: Removed unused totalWeeks variable
5. Optional Chaining: Added proper optional chaining for impact.financial?.riskLevel

Key Improvements

1. Comprehensive Type Testing: Full coverage of CIA type system with all edge cases
2. Format Utils Testing: All formatting functions tested with various input scenarios
3. Business Value Testing: Complete coverage of ROI, timeline, and cost calculations
4. Service Integration: End-to-end workflow testing across multiple services
5. Edge Case Handling: Extensive testing of error paths and boundary conditions
6. Real-World Scenarios: Practical test cases matching production use patterns

Test Quality

• All tests follow existing patterns and conventions
• Proper use of mock data providers
• Tests validate behavior, not implementation
• Clear, descriptive test names
• Comprehensive edge case coverage
• Integration tests verify cross-service data flow
• TypeScript type-safe throughout

@copilot continue some test break, make sure all code is correct and system working or fix broken test if test is not correct

Fixed all TypeScript compilation errors in the test files. The issues were:

1. Service constructors missing required dataProvider parameter
2. Wrong method signatures for getSecurityMetrics() and getROIEstimates()
3. Industry type typo ("finance" → "financial")
4. Optional chaining needed for impact.financial

All 1201 tests passing ✅ and build successful ✅
