feat(http): device-type endpoints + type_id on device create/patch

- GET /api/device-types — built-ins only (read-only).
- GET /api/projects/:pid/device-types — built-ins + project-custom merged.
- POST/PATCH/DELETE /api/projects/:pid/device-types — project-custom only.
  Mutating a built-in row returns 403 via the new ErrForbidden → 403 map
  in writeError.
- devicePatch / deviceCreate JSON shapes accept type_id (tri-state for
  PATCH via the existing parseFrameRef helper applied to type_id too).
- POST /api/projects/:pid/devices with type_id seeds ports in one tx
  server-side; response carries the device row + the snapshot will then
  carry the new ports.
