fix: 首席架構師審查修復 — i18n/CD/時區/死碼清理

P0 前端 i18n 合規 (6 檔案):
- settings/page.tsx: 全面改用 useTranslations('settings')
- auto-repair/page.tsx: 30+ 處硬編碼改用 t('autoRepair.*')
- sidebar.tsx: sectionLabel 改用 tSection()，aria-label 國際化
- openclaw-panel.tsx: STATUS_MESSAGES 改用 tPanel()，Production 改用 tBrand
- alerts/page.tsx: StatPill label 改用 t('incident.severity.*')

P1 CD Pipeline:
- cd.yaml: runs-on 改 self-hosted (ADR-039)
- Telegram Secret 注入失敗改為 exit 1 (ADR-035)
- kubectl patch op:replace → op:add (首次部署相容)

P2 後端:
- langfuse_client.py: 移除 v4.x 死碼分支 (SDK 鎖定 <3.0.0)
- ai.py: 標記 TODO(R4) Router 瘦身
