feat: Implement distributed database using Mycelium

- Refactor database streamer to support multiple workers.
- Add master node to manage and distribute data updates.
- Implement worker nodes to receive and apply updates.
- Remove unnecessary slave node.
- Improve error handling and logging.
- Use base64 encoding for JSON compatibility in data transfer.
