Production installs use docker-compose.production.yml (the README's documented
path, pinned GHCR images, no dev services), but the dashboard's update
instructions emitted bare `docker compose pull` / `up -d`. Bare `docker compose`
operates on docker-compose.yml — a different, build-based stack — so a
production user who followed the steps:
- never pulled/recreated their real containers (stayed on the old version,
e.g. stuck on 3.44.0 after "updating" to 3.45.2), and
- started the dev-only mailhog service that docker-compose.yml defines
(reported restart-looping).
The backend runs inside a container and can't stat the host's compose files, but
docker-compose.production.yml passes PICPEAK_RELEASE_CHANNEL into the backend env
and docker-compose.yml does not. detectEnvironment() now derives
isProductionCompose from it, and the Docker update steps prepend
`-f docker-compose.production.yml` when set. The non-production branch keeps the
bare commands but the warning now tells users to add `-f docker-compose.production.yml`
if they installed with it.
Also gates the mailhog service in docker-compose.yml behind a `dev` compose
profile so a plain `docker compose up -d` never starts it (opt in with
`docker compose --profile dev up -d`). Nothing depends on it (SMTP_HOST comes
from .env), so gating is safe. Verified: `docker compose config` lists mailhog
only with `--profile dev`; production compose is unchanged.
Adds unit tests for the production-vs-default command generation.
