Replace the old IMAGE_VERSION_FILE/RUNNING_VERSION_FILE mechanism with a single deploy fingerprint (image_version:sha256(chatmail.ini)) stored at /etc/chatmail/.deploy-fingerprint. On restart, if the fingerprint matches the last successful deploy, skip cmdeploy run entirely. The fingerprint lives on the container's writable layer. On fresh containers, setting CMDEPLOY_STAGES non-empty in env forces a deploy run regardless of fingerprint. Also narrow the /home volume mount to /home/vmail.
