Add Docker-based deployment: Dockerfile based on systemd image,
docker-compose.yaml, build script, entrypoint, external certificate
monitoring, CI workflow, and documentation.
This builds on the chatmaild/cmdeploy preparation in the previous
commit (j4n/docker-prep-chatmail) which added the env-var-driven
feature flags (CHATMAIL_NOSYSCTL, CHATMAIL_NOPORTCHECK, CHATMAIL_NOACME)
and @local deployment support needed by the container.
This is commit 2 of 3 to merge squashed changes on j4n/docker and docker
branches, original commits were beef0ec..606f36e
Architecture overview (mostly by original author Keonik1):
- Debian-systemd image wrapping the existing cmdeploy install
- Host networking to not manually expose the many ports needed
- Config via MAIL_DOMAIN env var or (new) mounted chatmail.ini
- New: cmdeploy stages: install at build, configure+activate at startup
- New: Monitoring service for external certs via systemd timer (chatmail-certmon)
- New: Image version tracking for automatic upgrade detection (cm + config hash)
- New: docker-compose.override.yaml pattern for user customizations
- New: GitHub Actions CI for ghcr.io image builds
Traefik reverse-proxy support is prepared but the specific files are
excluded from this PR and will be submitted separately.
TODO:
- [ ] Pull out CHATMAIL_NOACME as PR #855 introduced a proper mechanism
- [ ] Check if underlying image could be based on regular debian-slim
images with a step to enable systemd, similar to

* cleanup: remove CFFI deltachat bindings usage, and consolidate test support with rpc-bindings
major simplification: all chatmail fixtures used in the test are now created inside the cmdeploy plugin,
and do not inherit anything from other fixture machineries, let alone the legacy deltachat CFFI ones.
also fix that pytest report headers show correct chatmail domains under test
