Add aftersales work order frontend pages

- Public scan-to-confirm page (/aftersales/:sn) with phone last-4 verification
- Admin list + detail pages with state machine, QR generation, reassign, force-close
- PublicLayout extracted from PublicQuery so both pages share logo + 备案 chrome
- PublicQuery auto-redirects scanned zjbf-sh-* serials to the aftersales page
- AdminLayout: new 售后工单 menu entry
