Adds a new "نمای کلی و نمودارها" tab to the financial reports page with
KPI cards, daily/weekly income-trend and monthly breakdown charts, a
payment-status doughnut, a due-date cash-flow forecast chart, and full
per-class income and upcoming-payments tables — backed by chart.js /
vue-chartjs and the new /financial-reports/admin/analytics endpoint.
Adds payout configuration fields (percentage/hourly + per-session
expense allowance) with a live payout preview to the class form,
a new Financial Reports page (per-class and date-range/monthly tabs,
per-session drill-down dialog) with reusable stat cards, and an
Institutional Expenses management page. Registers routes, sidebar
navigation, and permission constants for the new financial_reports
and expenses permissions.
