fix: TypeScript errors and add clickable class actions

- Fix isEquipped -> equipped property name in export-character-html.ts
- Remove unused imports in character-sheet-page.tsx
- Remove unused variable in alchemy-tab.tsx
- Add on-demand German translation for feats in feats.service.ts
- Make class actions clickable in actions-tab with FeatDetailModal
- Add (Englisch) hint for untranslated feat descriptions
