docker: auto-detect image upgrades and include install stage

Without version tracking, if a new image requires the install stage
(e.g. new package versions), the default configure,activate will skip
it and potentially fail silently.

At build time, the git hash is written to /etc/chatmail-image-version.
At runtime, setup_chatmail_docker.sh compares it against the persisted
/home/.chatmail-running-version (survives container restarts via the
/home volume). If they differ, the install stage is automatically
prepended to CMDEPLOY_STAGES. After a successful deploy, the running
version is updated.
