fix: update deployment script for automatic .env loading and docker compose v2

Fixed multiple issues with the deployment automation:

1. Deploy script now auto-loads .env file:
   - Added automatic sourcing of .env at script start
   - Uses set -a/set +a to export all variables
   - Ensures HARBOR_PASSWORD and other vars are available

2. Updated docker-compose to docker compose (V2):
   - Changed all docker-compose commands to docker compose
   - Fixes "command not found" errors on modern Docker

3. Updated systemd service configuration:
   - Changed to use EnvironmentFile instead of hardcoded values
   - Loads variables from /srv/docker-compose/basil/.env
   - Changed user from root to pkartch for security

These changes enable successful automated deployments from CI/CD webhook
triggers, pulling images from Harbor registry and restarting containers.
