Replace abstract tooltip explanations with practical troubleshooting guide

- Remove unhelpful technical descriptions with meaningless numbers
- Add problem-solution pairs with specific value recommendations:
  • Photos not detected → increase Tolerance to 30-50
  • Too many false detections → increase Minimum Area to 15000-20000
  • Photos cropped tight → increase Border Size to 5-10
  • Tilted photos → lower Angle Threshold to 5
  • Dust detection → increase Minimum Contour Area to 1000

- Improve setup tips with concrete measurements:
  • Use white/light backgrounds
  • Leave 1cm gaps between photos
  • Scan at 300+ DPI
  • Try defaults before adjusting

Now users get actionable solutions instead of abstract technical jargon.
