fix: source .env file before executing import scripts

Added 'set -a && source .env && set +a' at the beginning of import scripts
to load environment variables from .env file.

This ensures DB_USER and SEXY_DB_NAME are properly set before executing
docker commands, regardless of whether arty exports them or not.

- set -a: enables automatic export of variables
- source .env: loads variables from .env file
- set +a: disables automatic export
