fix(telegram): 按鈕回覆靜默兩大根因修復

問題一：ai_advisory_* 按鈕（容量預測/合規等）
  - 按下後只發 toast（2-3 秒消失），群組永無回覆
  - 修法：_handle_ai_advisory_action 加 message_id 參數，
    answer_callback 後額外 sendMessage reply 到原卡片

問題二：已解決告警再次點「批准」
  - sign_approval early-return（status != pending）但
    _notify_approval_result 仍發「⚡ 執行中...」→ 永無後續
  - 修法：僅 approval.status == APPROVED 時才發「執行中...」
    其他終態改發「ℹ️ 此告警已處理（狀態：...）」並 return
