Forward the new dismissal toggle into the container

In the normal deployment path the bot runs inside the compose service, but docker-compose.yml uses an explicit environment: list with no env_file, and the workflow env writer only emits the existing 2FA variables. As a result, setting IBKR_DISMISS_SMALL_GATEWAY_DIALOGS=no in the host .env or repo variables never reaches 2fa_bot.py, so operators cannot disable this new broad IBKR Gateway dialog dismissal without editing the compose file itself.
