feat(ia): IA גל-2 — איחוד-משטחים: ערוץ-למידה אחד · /operations⊇/diagnostics · MET-2/3 (#131, X17)

גל-2 מבקלוג #127 — איחוד-משטחים לפי משטח-היעד של X17. מקיים INV-IA1/IA3/IA4 +
דלתות-הספ (X6 INV-UI7/8, 07-learning §0.4, 00-constitution G2). שומר G10/INV-LRN1
(לא הוסר שום שער-אנושי — רק שער/דגל כפול).

א) תיבת-אישור אחת (INV-IA1): כרטיסי "אישור הלכות"+"פסיקה חסרה" ב-/operations
   מצביעים ל-/approvals (לתיבת-האישורים ←) — /operations מנטר, /approvals מחליט.

ב) ערוץ-למידה אחד (INV-IA3): הוסר applied_to_skill end-to-end —
   - UI: כפתור "סמן כ'אומץ'" + badge "אומץ" ב-lessons-tab; badge ב-curator-portrait.
   - API: LessonPatch, _lesson_to_json, patch call, curator recent_findings (→review_status).
   - db.py: list/add/update_decision_lesson לא בוחרים/כותבים applied_to_skill;
     הפרמטר הוסר. העמודה+אינדקס נשמרים (back-compat, ללא migration), מסומנים DEPRECATED.
   - types: DecisionLesson/LessonPatch/CuratorFinding.
   review_status='approved' = הסטטוס היחיד "זורם-לכותב" (INV-LRN1, #126).

ג) MET-2/3 lost-update (INV-IA3): _append_methodology_override רץ עכשיו בטרנזקציה
   אחת עם SELECT ... FOR UPDATE — אין read-modify-write מתפצל מול עורך-המתודולוגיה
   או promote מקביל. /methodology = העורך-הקנוני; promote מבטל את ה-cache (גל-1 MET-1).

ד) /operations⊇/diagnostics (INV-IA4): גוף /diagnostics חולץ ל-<SystemHealthSection/>
   ומורנדר ב-/operations תחת "בריאות-מערכת". /diagnostics → redirect ל-/operations.
   /diagnostics הוסר מהניווט. משטח-ניטור יחיד.

ה) דלתות-ספ (≥3 מקורות ב-X17, אושר ע"י חיים /goal):
   - X6: INV-UI7 (aggregate=SSoT, mutation מבטל queryKey) + INV-UI8 (render-or-remove, חלקיות).
   - 07-learning §0.4: שער-אחד + טרנזקציה-אחת + applied_to_skill מוסר.
   - 00-constitution G2: תאום-המתודולוגיה כהפרה-ידועה-ממותנת.
   - X17 דלתות-ספ סומנו ✅ קודדו.

בדיקות: py_compile app.py + db.py ✓ · tsc --noEmit ✓ · eslint ✓ (לבד מ-learning-panel:109
קיים-מראש). next build נכשל ב-worktree רק בגלל symlink (Turbopack) — Docker/CI תקין.
api:types יתרענן בדפלוי (curator/lessons אינם response-modeled; הטיפוסים יד-כתובים עודכנו).
