chore: clean up environment variable usage and formatting in configuration files

- Updated docker-compose.yaml to use double quotes for version and port mappings.
- Removed DEPLOYMENT_PROVIDER from global environment variables in turbo.json and Dockerfile.
- Adjusted dashboard build command in package.json to remove DEPLOYMENT_PROVIDER.
- Cleaned up .env.example by removing the DEPLOYMENT_PROVIDER comment.
- Simplified SvelteKit adapter condition in svelte.config.js.
