ADR-013 Phase 4: relocate the remaining 9 plugin frontends (all 13 done)

Relocate warranty, measuringtools, network, printers, usb, notifications,
computers, and slides into plugins/<name>/frontend/. Each plugin's views are
pulled from wherever they lived (own dir, plus the shared views/settings/,
views/reports/, views/print/ dirs, and top-level views) into the plugin's
frontend/views/, and its route file becomes the self-contained routes.js.

Handled the messy cases:
- computers: name mismatch (its views live in views/pcs/) - moved by following
  the route file's own imports, so the dir name did not matter. Its OS/access-
  protocol/PC-type settings views move with it (only computers.js routed them).
- network: NetworkHub's sibling sub-views (NetworkDevicesList, SubnetsBrowse,
  not directly routed) moved too so its `./` imports resolve.
- printers: the qrLogo helper is SHARED with core AssetLabel, so it stays in
  views/print/ and PrinterQR imports it via @/views/print/qrLogo.
- slides: route file is toplevel-only (TVDashboard); SlideManager stays core
  (core.js routes /settings/slides).

frontend/src/views/ now holds only core views; frontend/src/router/routes/ holds
only core.js. All 13 plugins are self-contained under plugins/<name>/frontend/.
Verified live: Network (hub + moved sub-views), Computers (name mismatch),
GE-Enforce (helper), printedparts all render from their staged frontends. Build +
58 vitest + naming green.
