Changed

• Container installs must now set HOST_DOWNLOAD_PATH and HOST_LOG_PATH in
  .env. docker-compose.yml no longer hardcodes the host directories behind
  its two mounts; it reads them from the same .env the app is given. Add both
  before pulling this change, set to the directories the compose file used to
  name. Adding them first does no harm, because the old compose file ignores them
  and so does the app. Pull first and docker compose refuses to start until
  they are set.

  They have no default, on purpose. A default would put backups somewhere nobody
  chose, and clean would then expire an empty directory while the real backups
  kept ageing, with every run reporting success. Unset, docker compose stops
  and names the missing variable. A path that does not exist is refused too,
  rather than created as an empty directory, so a typo fails the same way — and
  both directories must already exist. DOWNLOAD_PATH and LOG_STORAGE_PATH are
  unchanged: they still name the container side. A compiled binary ignores all
  of this.
