Update docker-compose.prod.yml to enhance n8n service configuration (#82)

- Added `restart: unless-stopped` to the n8n service for improved
reliability.
- Introduced environment variables `N8N_DEFAULT_BINARY_DATA_MODE` and
`N8N_BINARY_DATA_STORAGE_PATH` to configure binary data handling.
- Cleaned up unnecessary whitespace in the configuration file for better
readability.

Docs:
https://docs.n8n.io/hosting/configuration/environment-variables/binary-data/

These changes enhance the stability and functionality of the n8n service
in the production environment.
