feat(homeassistant): Add initial Docker Compose setup for Home Assistant

This commit introduces the `docker-compose.yml` file for deploying Home Assistant.

The configuration defines the `homeassistant` service using the `linuxserver/homeassistant` image. It sets up:
- Persistent data storage at `/mnt/docker/home/homeassistant/data`.
- Environment variables for user IDs (PUID, PGID) and timezone.
- Required capabilities (`NET_ADMIN`, `NET_RAW`) for network functionality.
- Integration with existing `pangolin-home` and `teslamate-internal` external networks.

This allows for easy deployment and management of the Home Assistant instance.
