Replace the Schnell/Wizard tab layout with a unified flow:
1. Proceeding type selection via compact clickable cards grouped
by jurisdiction + category (UPC Hauptverfahren, im Verfahren,
Rechtsbehelfe, Deutsche Patentverfahren)
2. Vertical deadline rule list for the selected type showing name,
duration, rule code, and acting party
3. Inline expansion on click with date picker, auto-calculated due
date (via selected_rule_ids API), holiday/weekend adjustment
note, and save-to-case option
Old DeadlineCalculator.tsx and DeadlineWizard.tsx are no longer
imported but kept for reference.
