Improve cancelled order display and add notes to order detail

- Add "Catatan" field display in consulting order detail page
- Add dedicated "Cancelled Order" section with rebooking option
- Update status alert to show proper message for cancelled orders
- Refactor edge function to focus on calendar cleanup only
- Set payment_status to 'failed' when auto-cancelling expired orders
