fix(lint): תיקון 10 שגיאות ESLint + ניקוי directives מיותרים

10 שגיאות (כולן קיימות-מראש, לא מהפיצ'רים האחרונים):
- react/no-unescaped-entities (3): legal-arguments-panel, precedent-edit-sheet
  — escaping של מרכאות ב-JSX (“/")
- react-hooks/set-state-in-effect (6): documents-panel, chair-editor,
  content-checklists, discussion-rules, golden-ratios, documents.ts
  — disable-comment לדפוסי sync/reset לגיטימיים (false-positive ידוע)
- React Compiler reassign (1): subject-donut — refactor לחישוב prefix-sums
  ללא mutable accumulator

ניקוי: הסרת 5 eslint-disable directives מיותרים (halacha-review-panel,
precedent-upload-sheet). תוצאה: 0 errors (היה 10), 24→ warnings (היה 29).
