Remove profiles from worker service in both docker-compose.yml and
docker-compose.dev.yml so the worker starts automatically with
`docker compose up`. This fixes the issue where verification SMS and
the scheduler timer were not working because the worker was never
started. The bot remains as an optional profile.
Update README to reflect the change.
