⭐ feat(maitred): Update maitred - hookup to the API (#198)

## Description
We are attempting to hookup maitred to the API
Maitred duties will be:
- [ ] Hookup to the API
- [ ]  Wait for signal (from the API) to start Steam
- [ ] Stop signal to stop the gaming session, clean up Steam... and
maybe do the backup

## Summary by CodeRabbit

- **New Features**
- Introduced Docker-based deployment configurations for both the main
and relay applications.
- Added new API endpoints enabling real-time machine messaging and
enhanced IoT operations.
- Expanded database schema and actor types to support improved machine
tracking.

- **Improvements**
- Enhanced real-time communication and relay management with streamlined
room handling.
- Upgraded dependencies, logging, and error handling for greater
stability and performance.
