Add Bookings & Revenue reporting module

New modules/reporting Filament page: filterable bookings table (travel
date range, status, route, channel) with CSV/Excel export. Report
columns include booking ref, route, passenger name/count, price,
best-payment status/amount, and driver info, plus a TOTAL row summing
passenger count, price, and payment amount in both export formats.

- BookingsRevenueExport backs both CSV and XLSX via maatwebsite/excel
  ^4.0 (the only version compatible with PHP 8.5; 3.1.x caps
  phpoffice/phpspreadsheet below 8.5).
- CSV export writes a UTF-8 BOM so non-Latin passenger names (Burmese)
  open correctly in Excel.
- New view_reports permission (super_admin/admin/support) gates the
  page; new indexes on bookings.travel_date/status/created_by_channel
  and payments.completed_at support the report's filters.
