feat(07-01): wire dashboard data and add /packages listing page

- Dashboard queries 5 most recent Printer records and 5 most recent driver-assigned ones
- New /packages route lists printers with drivers, with intunewin/ninja download links
- packages.html template extends base.html with Pico grid table
- Dashboard printer/package items now link to detail pages
- Quick action buttons wired to real routes (removed aria-disabled)
