feat(telegram): AI 鏈路透明化 — 告警訊息顯示 OpenClaw + Tool Calling 模型/後端

- nemotron.py: 偵測 OllamaToolProvider vs NvidiaProvider，記錄 tool_model/tool_backend
- openclaw.py: 傳播 nemotron_tool_model/nemotron_tool_backend 到 proposal
- decision_manager.py: 從 proposal_data 提取並傳給 send_approval_card()
- telegram_gateway.py: TelegramMessage 新增兩個欄位，format_with_nemotron 顯示
  "🔧 Tool Calling: llama3.1:8b (Ollama 本機)" 或 "NVIDIA 雲端"
