fix(vision): include remote camera in isVisionSetupComplete check

The isVisionSetupComplete flag was only checking for local camera
setup (cameraDeviceId + calibration), which caused remote camera
mode to be treated as "not configured" even when connected.

Now considers vision setup complete if either:
- Local camera: has camera device AND calibration
- Remote camera: has remote session ID (phone handles calibration)
