feat(case-ui): כרטיס "הפקת מסמכים" עם 3 כפתורי-הפק דטרמיניסטיים (#214)

מוסיף כרטיס "הפקת מסמכים" בראש טאב "טיוטות והערות" (mockup 26 — תוספת ל-18h),
תוספת לעמוד הקיים, כל הסקשנים נשמרים.

- כפתור 1 "הפק סיכום מנהלים" → endpoint חדש POST /generate/party-claims-summary
  → CEO wakeup סטרוקטורלי action="party_claims_summary" (שלב H2, host-side).
  Polling: GET /research/party-claims-summary (200=מוכן → פתח/DOCX).
- כפתור 2 "הפק טיוטה של טענות הצדדים" → endpoint חדש POST /generate/interim-draft
  → CEO wakeup action="interim_draft" (שלב H, host-side).
  Polling: רשימת ה-exports עד שמופיע טיוטת-ביניים-{case}-vN.docx.
- כפתור 3 "הפק טיוטת החלטה מלאה" → ה-useExportDocx הקיים (in-container, ללא LLM);
  הועבר מהבאנר (כפתור "הפק DOCX" הוסר משם — אין כפילות). disabled+title כשאין
  בלוקים כתובים (isDraftReady).

מסלול-עירור יחיד דרך ה-Platform Port (pc_wake_ceo_for_action) → API helper
/api/agents/{id}/wakeup, לעולם לא DB insert. Israel-time + cache-invalidation.

Invariants: G12 (מגע-Paperclip רק ב-paperclip_client + agent_platform_port;
leak-guard ירוק) · G2 (אין מסלול-עירור מקביל — שימוש חוזר ב-pc_request הקיים) ·
G10 (הפקה מגודרת-יו"ר/CEO) · INV-UI9 (Asia/Jerusalem) · X6 (UI↔API contract).

+/**
+ * Document-generation domain hooks (TaskMaster #214).
+ *
+ * The "הפקת מסמכים" card in the case "טיוטות והערות" tab fires two deterministic,
+ * host-side generation actions through the CEO (structured-action wakeup):
+ *   • party_claims_summary → an executive summary of the parties' claims
+ *   • interim_draft        → a partial draft (blocks ה–ט, up to the discussion)
+ *
+ * Generation runs on the host (claude_session → claude -p), NOT in the container,
+ * so the trigger endpoints return 202-accepted and the UI POLLS for completion:
+ *   • summary → GET /api/cases/{n}/research/party-claims-summary (200 = ready)
+ *   • interim draft → the exports list grows a "טיוטת-ביניים-{n}-vN.docx" file
+ *     (polled via useExports — see exports.ts).
+ *
+ * The full-decision export ("הפק טיוטת החלטה מלאה") is NOT here — it reuses the
+ * existing in-container useExportDocx (exports.ts), no LLM, no wakeup.
