voucher functionality
Allow to assign vouchers for specialist visit to the subject.
Each voucher should have:
- serial number with checksum - I was thinking about 4-5 digits for the serial number + 2 digits for checksum
- issue date
- expiry date (for now it's issue date+3 months)
- use date (automatically filled when status changed to used)
- voucher type
- status: new, used, expired, deleted (only for internal data consistency)
- feedback from Voucher Partner: free text
- voucher partner
