Populate null earnings fields with safe margin calculations

Browse Source 
Add calculated values for gross_profit_margin, operating_margin, and
other_operating_expenses to provide more comprehensive financial data
matching fiscal.ai methodology.

Implementation:
- Add calculate_gross_profit_margin() function for (Gross Profit / Revenue) × 100
- Add calculate_operating_margin() function for (Operating Profit / Revenue) × 100
- Add calculate_other_operating_expenses() to derive from components
- Include comprehensive unit tests with edge case coverage

Safety features:
- Null propagation using ? operator for missing data
- Division protection with f64::EPSILON checks
- Proper handling of negative values (losses)
- Semantic distinction between Some(0.0) and None

Validation: MSFT FY2024 data shows 68.8% gross margin and 45.6%
operating margin, matching fiscal.ai calculations.
