feat(learning): FU-2 UI — התלבטות-הפאנל במסך-אישור היו"ר (#133)

מציג את התלבטות 3-השופטים (הצבעה+נימוק לכל לינאז' + ה-verdict)
בתוך כרטיס-האישור הקיים של דפנה ב-/precedents → "ממתין לאישור",
כדי שהכרעתה — תווית-הזהב שהלולאה לומדת ממנה — תהיה מיודעת ב*למה*
הפאנל נחלק. אושר ב-Claude Design (כרטיס 18-halacha-deliberation).

Backend (opt-in, ברירת-מחדל off — קוראים קיימים לא מושפעים):
- db.list_halachot(include_panel_round=True) → _annotate_panel_rounds
  מצרף את הסבב האחרון מ-halacha_panel_rounds (DISTINCT ON, latest).
- GET /api/halachot?include_panel_round=true.

Frontend:
- Halacha.panel_round (טיפוס ידני; ה-endpoint מחזיר dict).
- תור-הסקירה (useHalachotPending) מבקש include_panel_round בשני
  הדליים (clean=keep, needsFix=nli/entailed).
- רכיב PanelDeliberation: טבלת 3-שופטים (✓נתמך/✗הכלל-חורג + נימוק),
  תג-ורדיקט "פיצול 2:1", ושורת "שורש המחלוקת" (קפדני↔תמצית) רק
  בפיצול-entailment. מוזרק אחרי רשת הכלל/ציטוט.

שער יחיד — אין עמוד/שער חדש (INV-IA/G10); display-only, לא נוגע
ב-review_status. ולידציה: py_compile + tsc --noEmit + eslint נקיים;
בדיקה פונקציונלית: panel_round מצורף ל-6 שיש להן סבב, 1994 בלי.

חלק מ-#133 (FU-2). דורש deploy + (אופ') npm run api:types אחרי.
