Update preview modal with design-type-specific buttons

- For disc designs: show 'Import into Disk 1' and 'Import into Disk 2' buttons
- For templates: show 'Print / Save PDF' button
- Buttons are built dynamically based on design type
- Disc imports automatically switch to template mode
- Both designs still have 'Save JSON' option
