迁自 park-desktop/backend/app：config(数据目录→serverdata/park)/storage/sim_engine/ mqtt/event_bus + 精简 routers(health/settings/config/dashboard/park/companies/display/ events) + app.py 子应用(lifespan 起 MQTT hub+tick 线程, include_router prefix=/park)。 dispatcher.py 增 ROUTE_PARK_PREFIX + _prefix_app，与 app.training(/api)、app.main 分流。 pyproject 增 paho-mqtt(MQTT 必需)。AI/知识库/语音/视觉重模块延后全量迁入。
