Rewrite court detection: find ALL court lines, not just 4 corners

Browse Source 
- Detect white lines via color threshold + Canny + Hough
- Group/merge nearby parallel segments into court lines
- Classify as 'across' (baseline, kitchen) and 'along' (sidelines, service)
- Match detected lines to known court geometry for solvePnP
- Debug image shows: raw segments (gray), merged across (yellow), along (magenta)
- Show line counts + matched points in calibration UI
