feat: PDF ticket generation

- Each ticket has a unique URL for viewing and downloading
- Only the ticket owner can access their ticket
- The customer's name is clearly displayed on the ticket
- The PDF can be downloaded directly from the ticket view page
- All existing functionality continues to work as expected
