feat(notifications): document SMTP env and translate channel strings

Add the webhook + email Settings copy and the admin notification-health
panel labels across all six locales. Add the SMTP_* operator vars to the
env manifest (all-or-none: HOST + PORT + FROM enable the channel,
USER/PASS optional), to .env.production.example, and to the docker-compose
environment whitelist so an operator's .env values actually reach the
container.
