refactor(docker): migrate service startup from Artisan commands to shell scripts

Remove custom Artisan console commands (Horizon, Nightwatch, Scheduler) and
refactor service startup logic directly into s6-overlay shell scripts. Check
environment variables from .env instead of routing through Laravel config.

Services now sleep when disabled instead of exiting immediately. Both
development and production environments updated consistently.
