Dockerfile CMD carries `--reload` for dev hot-reload (app/ bind-mounted in
docker-compose.yml). In prod the same image ran with --reload too — prod logs
showed "Started reloader process [1] using WatchFiles" — wasting a file-watcher
and risking a reload mid-request on an immutable image.
Add a prod-only `command:` override running uvicorn without --reload. Keep it a
single worker (no --workers): the in-app scheduler (app.services.scheduler,
tick=60s) lives in the backend process, so multiple workers would duplicate
scheduled jobs (cian/rosreestr would fire N times). Dev is untouched (no command
override there → still inherits the Dockerfile --reload).
