fix(t126): 萃取引擎/金鑰改每帳號一份——多帳號不再互相覆蓋

leo：「2 個 CF 帳號一個填 gemma4 一個填 Mistral，daemon 會用誰的？別人也加就會有一樣的疑問」實證：金鑰只有機器層一份 ⇒ 後連的覆蓋前一個。修：AccountConfig 加 Extractor/GeminiAPIKey/LLMModel；帳號層優先、空值繼承機器層；既有 config 遷移（頂層金鑰複製到各帳號，冪等）；連線只寫該帳號不覆蓋機器層；托盤帳號標題顯示「· Gemini」/「· Claude」（一眼看出誰用誰）。三模組 go test 全綠（總管親跑）。（實作＝子 CC；驗證+commit＝總管）
