- Remove fallback corner estimation (_estimate_corners_from_net)
- Gate YOLO detection behind calibration check in detection_loop
- Add calibration overlay UI with prominent Calibrate button
- Disable Court/Trajectory tabs until system_ready
- Skip trajectory/VAR/event polling when uncalibrated
- Add system_ready flag to calibration status API
