fix: Export env vars before docker-compose in deploy script

Problem: docker-compose substitutes ${VAR} from shell environment, but
env variables from secrets/*.env files were not exported. This caused
RabbitMQ RABBITMQ_DEFAULT_USER/PASS to be empty, resulting in auth failures.

Solution: Use 'set -a' to auto-export all variables, source env files,
then 'set +a' before running docker-compose commands.

This fixes RabbitMQ authentication errors in production worker.
