CronJob containers import src.config.Settings() at startup, which requires
WEB_SECRET_KEY. Only the Deployment set it; the 5 CronJobs (git-sync,
morning-briefing, evening-summary, waiting-followup, deadline-checker) crashed
at import with a pydantic ValidationError, causing restart loops (e.g.
myorg-git-sync ~5 restarts/15m). Pull WEB_SECRET_KEY from the existing
myorg-assistant-secret so the cronjobs start cleanly.
CronJob pods were stuck in ImagePullBackOff because they referenced
the local-only image 'myorg-assistant:latest' which is not present
on the node. Switch all 5 cronjobs to the Gitea registry image
git.rogi.casa/roger/myorg-assistant/myorg-assistant:fcf79bf
(matching the Deployment), set imagePullPolicy: Always, and add
imagePullSecrets: gitea-registry so they can authenticate to the
private registry.
