Migrate frontend to plugin-based asset architecture

- Add equipmentApi and computersApi to replace legacy machinesApi
- Add controller vendor/model fields to Equipment model and forms
- Fix map marker navigation to use plugin-specific IDs (equipmentid,
  computerid, printerid, networkdeviceid) instead of assetid
- Fix search to use unified Asset table with correct plugin IDs
- Remove legacy printer search that used non-existent field names
- Enable optional JWT auth for detail endpoints (public read access)
- Clean up USB plugin models (remove unused checkout model)
