feat(reports): add Excel export to balance monitoring endpoint
Add ?export=excel support to GetBalanceMonitoring. Creates a new repport.balance_monitoring.export.go with a 2-row merged header layout matching the UI (Penjualan Ayam and Penjualan Telur grouped columns), a totals row, red styling for negative Saldo Akhir, and frozen panes below the header rows. Exported data reflects all active query filters. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
