fix(web): 驗收報告 6 個問題修復

1. [Medium] Metrics Strip [object Object] — 移除 pendingApprovals 陣列直接渲染
   + label 硬編碼改 i18n (activeIncidents/serviceHealth/todayIncidents 等)
2. [Low] KB GET /{id} 不過濾 archived — get_by_id 加 status != ARCHIVED
3. [Low] favicon.ico 404 — 新增 NemoClaw SVG favicon + layout metadata
4. [Medium] auto-repair console errors — fetchEval 加 try-catch 靜默處理
