feat: implement permanent broadcast message functionality

- add SendPermanentBroadCastMessage to continuously send updates
- refactor BroadcastMessage to use a shared Message struct
- update pomodoro logic to modify broadcast.Message directly
- adjust client command handling to use broadcast.Clients map
- enhance ServerMessage struct with "Ongoing" and "Paused" fields
