Remove update_ini.sh and the env-var-to-ini pipeline. The container now
has two config modes:
- Simple: set MAIL_DOMAIN in .env, container generates chatmail.ini
with defaults via `cmdeploy init` on first start.
- Advanced: mount a custom chatmail.ini into the container; the init
step is skipped when the file already exists.
This eliminates the fragile FORCE_REINIT_INI_FILE / INI_CMD_ARGS
machinery and the env vars that duplicated chatmail.ini settings
Also add *.ini and .env to .dockerignore so local config files
don't leak into the image.
Move the CMDEPLOY_STAGES=install execution into the Dockerfile these
operations baked into the image layer. On container start, only
configure and activate stages run by default. Users can override with
CMDEPLOY_STAGES="install,configure,activate" to force a full reinstall
without rebuilding the image.
Also fixes CERTS_MONITORING_TIMEOUT typo in docker-compose.yaml (was
"$CERTS MONITORING TIMEOUT"), and replaces the docker-commit workaround
in docs with CMDEPLOY_STAGES documentation.
