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。

"""server-core 统一入口（dispatcher）—— 对外生产服务 opc.pinesound.cn 单入口。

按「端口专属前缀」把请求分流到对应子应用，每端口自带前缀子路由、互不冲突：
|
||
/park/* → 园区子应用（app.park，大屏/MQTT/园区数据）
|
||
/api/*、/uploads/*、/SpXvScDiDT.txt → 培训子应用（app.training，独立 data/opc.db）
|
||
/auth /opc /admin /government /investor …→ 平台应用（app.main，身份 + 业务域，各端口子路由）
|
||
|
||
启动（server-core 目录）：
