Comprehensive Financial Dashboard

CFO membutuhkan dashboard KPI finansial bulanan dengan metrics:

1. revenue_growth: % perubahan dari bulan sebelumnya
2. expense_ratio: expenses / revenue * 100
3. profit_margin: (revenue - expenses) / revenue * 100
4. runway_months: cash_balance / monthly_burn_rate
5. health_status:
   • "Excellent" jika profit_margin > 30 AND expense_ratio < 60
   • "Good" jika profit_margin > 15
   • "Warning" jika profit_margin > 0
   • "Critical" jika profit_margin <= 0

Output yang diharapkan: bulan, revenue, expenses, profit_margin, expense_ratio, runway_months, health_status
