feat(adr-075): 修復 Telegram 動態按鈕 4 個斷點 + 新增 7 種告警分類

斷點 A: decision_manager 提取 alert_category/notification_type 傳入 send_approval_card
斷點 B: send_approval_card 新增參數並傳遞至 _build_inline_keyboard
斷點 C: 互動型通知 (TYPE-3/4/4D/8M) 禁止發 SRE 群組，防 nonce 洩漏
斷點 D: _CATEGORY_BUTTONS k8s_workload → kubernetes + 新增 6 類按鈕組

classify_alert_early 新增: alertchain_health, flywheel_health, storage,
devops_tool, external_site, ssl_cert, host_resource (從 infrastructure 分離)
Test: 52 classify + 664 total passed
