Two issues in paddle-kombi word merge:
1. Overlap threshold too strict: PaddleOCR "Stick" and Tesseract
"Stück" overlap at 48.6%, just below the 50% threshold. Both words
ended up in the result, overlapping on the same position.
Fix: lower threshold from 50% to 40%.
2. Text selection blind to confidence: always took PaddleOCR text
even when Tesseract had higher confidence and correct text.
Fix: when texts differ due to spatial-only match, prefer the
engine with higher confidence.
