feat: console_log.meshtastic 控制 packet 控制台输出；新增每客户端报文统计

- ConsoleLogConfig 增加 Meshtastic 字段（默认 true）；旧配置自动补齐
- meshtasticFilterHook 增加 packetConsoleLog；OnPublish 中根据开关调用
  新的 printMeshtasticRecord 输出可读单行（key=value、按 type 着色），
  替代原来的 JSON dump；事件型 printJSON 调用保持不变
- 新增 internal/mqttforward/ClientStats，按 client_id 累计 in/out 报文计数
- meshtasticFilterHook 多挂 OnPacketRead / OnPacketSent / OnDisconnect
  事件，用于增减计数；Provides() 同步声明
- AdminMQTTClient JSON 视图删除 RemoteHost/RemotePort，新增
  packets_in / packets_out；前端 types.ts、AdminDashboard.vue 同步更新
