feat(cases): תצוגת "פסיקה שצוטטה בהחלטה" בעמוד-התיק + שחזור חיווט-הרמס

UI שביקש חיים: בכניסה להחלטה רואים את הפסיקה שצוטטה בתוכה — מקושרת לספרייה
(קליק → /precedents/[id]) מול חסרה (סומנה אוטומטית להעלאה).

- web/app.py: GET /api/cases/{case}/citations — מהשורה internal_committee של
  ההחלטה ב-case_law → precedent_internal_citations: linked (join case_law) +
  missing (unresolved + האם flagged ב-missing_precedents).
- web-ui: lib/api/citations.ts (hook) + CitationsSection ב-drafts-panel
  (מוצג כשההחלטה בספרייה). מקושרת=ירוק/קליק, חסרה=ענבר "סומנה להעלאה".
- scripts/curator_apply_pipeline_branch.py: מקור-אמת לחיווט-הכפתורים של הרמס
  (ה-prompt חי רק ב-Paperclip DB). מקדים branch שמריץ את pipeline-ה-final
  ל-wake reason final_learning_*/final_halacha_* (HOME/DOTENV/DATA_DIR מוחלטים
  → מפתחות DeepSeek+Gemini + DATA_DIR נפתרים נכון). idempotent, שני הסוכנים.
  כבר הוחל ב-DB; הסקריפט לשחזור אחרי reset.

אומת: py_compile ✓ · tsc ✓ · החיווט אומת חי על 8126 (deepseek+gemini, dedup,
✓ pipeline הושלם). G2 (יכולת חסרה) · INV-LRN1/G10 נשמרים.
