Migrate PC form + collector off legacy Machine onto the asset/computer model

- PCForm saves/loads via computersApi (asset core + computer extension +
  primary IP in one call); PC Type now uses the dedicated computertypes table
  instead of MachineType, fixing the cross-table id mismatch.
- Collector (/api/collector/*) writes the Computer model: lookup by hostname
  or asset number, update loggedinuser/lastreporteddate/lastboottime + asset
  serial, installed apps via ComputerInstalledApp.
- Add computers.vendorid + modelnumberid (PCs carry make/model) and
  computerinstalledapps.installedversion; computer GET now includes
  communications. Wire COLLECTOR_API_KEY into config.

Retires the last write paths to the Machine model for PCs (ADR-001).
