feat(status-monitor): add websocket process manager and runtime metadata

extend server status payload with timezone, uptime, and process summary so
the monitor sidebar can show richer at-a-glance host context.

introduce process:list and process:signal websocket flows on active SSH
sessions, enabling on-demand process querying and terminate/kill actions
without adding new HTTP endpoints.

add a dedicated process manager modal in the frontend with search, refresh,
auto-refresh, and per-process actions, and wire localized labels for both
english and chinese.

enhance global connection fuzzy search scoring to include tag names as
secondary-weight fields while preserving primary host/name relevance.
