Fix consulting booking flow and export CSV format

1. CSV Export: Use raw numbers for Total and Refund Amount columns
   - Changed from formatted IDR (with dots) to plain numbers
   - Prevents Excel from breaking values with thousand separators

2. Consulting Booking Flow:
   - Fixed "Booking Sekarang" to navigate to order detail instead of redirecting to Pakasir
   - Payment QR code now displays in OrderDetail page
   - Consulting orders show slot details instead of empty items list
