fix: remove redundant LOGIN type, rename KILL label to \u6d3b\u8dc3\u5ea6

- LOGIN type duplicated with KILL (both use days_since_last_login)

- KILL label: \u5c01\u53f7\u89c4\u5219 \u2192 \u6d3b\u8dc3\u5ea6 (action is always \u5c01\u53f7/\u5220\u9664\u8d26\u53f7, type now describes monitoring category)
