Wire Stage 3 reports to real data

Created getReportData server action to fetch Orders, ManualSales, and
Expenses from database. Split reports page into server component (fetches
data) and client component (renders charts). Reports now display actual
business data instead of mock data - monthly profit, expense breakdown,
and cash flow tables.
