feat(09-03): add .ps1 script download routes and detail-page links

- Refactor install/uninstall/detect handlers into shared _*_response() helpers
- Add .ps1 route aliases: /scripts/install.ps1, /scripts/uninstall.ps1, /scripts/detect.ps1
- Add Scripts section to printer_detail.html inside {% if has_driver %} with 3 download links
- All 6 new tests green, full suite 106/106 passing
