chore: add Docker Compose configuration for Tailscale and rabbit services

- Introduce a new docker-compose-tailscale.yml file to define services for rabbit and Tailscale.
- Configure rabbit with migration support and fixed IP addresses within a custom network.
- Set up Tailscale with necessary permissions and environment variables for secure networking.
