refactor: Simplify PDF ticket download functionality

- Rename download_ticket action to download for consistency
- Use QR code lookup consistently in both show and download actions
- Simplify routes to use QR code pattern for both viewing and downloading
- Remove complex dual-lookup logic in favor of consistent QR code access
- Clean up route constraints and duplicate route definitions
