Fix admin order license generation bug

- Add 'Generate Licenses' button to order meta box for admin-created orders
- Add AJAX handler for manual license generation
- Show warning when domain is not set or order is not paid
- Handle partial license generation (when some products already have licenses)
- Update German translations for new strings (365 translated)
