changes. Frontend button in StepGroundTruth.tsx to mark/update GT.

The side-by-side panels used calc(100vh - 380px) pushing the Speichern/
Abschliessen buttons below the viewport. Reduced to calc(100vh - 580px)
and made the action bar sticky at the bottom.

Bold detection:
- Replace absolute threshold with page-level relative comparison
- Measure stroke width for all cells, then mark cells >1.4× median as bold
- Adapts automatically to font, DPI and scan quality
Save buttons:
- Fix status stuck on 'error' preventing re-click
- Better error messages with response body
- Fallback score to 0 when null
