fix(phase25): 首席架構師 Review R2 修正 (I1/I2/I3/I4/C3/M1)

I1: auto_repair_service — 失敗分支 anti_pattern task 補齊 _pending_tasks GC 防護
C3: drift_remediator — _kubectl_apply() 實作 resource_key 範圍過濾（修復虛設參數 bug）
M1: drift_remediator — _git_push() 標記 DISABLED，防止誤啟用
I2: drift.py — Telegram 通知移除失效的 adopt() 端點連結
I3: drift/page.tsx — handleScan POST body namespace→namespaces（對齊後端 DriftScanRequest）
I4: drift/page.tsx — 移除硬編碼英文字串，改用 t('loading')/t('highCount')/t('mediumCount')
i18n: zh-TW.json + en.json 補齊 drift.loading key
