Subject: [PATCH] fix: set DOCKER_API_VERSION=1.40 for watchtower compatibility
 with Docker 29

Watchtower's latest image defaults to API version 1.25; Docker 29 raised
its minimum supported client API to 1.40, causing watchtower to crash on
every start. Setting DOCKER_API_VERSION=1.40 via env var overrides the
default without requiring a newer watchtower image.
