fix(telegram): 移除 7 個 ghost button (3-part/無handler)

違規 buttons 一覽:
- flywheel_diag / flywheel_dashboard (META告警卡)
- pause_1h / ignore (業務告警卡)
- postmortem / escalation_ack / dr_manual (升級通知卡)
- secops_block_ip / secops_evict (SecOps 卡，spec=nonce 但用 2-part)

所有 buttons 均無 callback handler，點擊無回應 = 鬼魂按鈕
鐵律: 寧可沒按鈕，不可有死按鈕 (feedback_no_ghost_buttons.md)
