fix(myorg-assistant): add WEB_SECRET_KEY env to cronjobs to stop pydantic Settings validation crash

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.
