MCP-3 of milestone 461 "MCP server: Steward as an LLM-inspectable, LLM-operable hub". The /mcp tools run outside Quart's request pipeline, so the queries they share with the pages now live in plain functions that take an open session: - steward/hosts/service.py: uptime, status, monitors, agent metrics, agent overview (stale threshold passed in, not read from current_app), CPU sparks. - plugins/docker/service.py: bucket, container_history, host_map, list_containers, container_events, query_logs. - steward/alerts/service.py: active_alerts (also used by core/reports), list_rules, list_maintenance_windows. - steward/monitors/service.py: monitor_rows (was routes._rows_data). Routes are repointed and render the same data. One behavior fix rides along: the container-log search now escapes % and _ so they match literally instead of acting as LIKE wildcards.
