Cronjob pods were stuck in ImagePullBackOff because they referenced bare
image name 'myorg-assistant:latest' (no registry, no pull secret).
Updated all 5 cronjobs to use git.rogi.casa/roger/myorg-assistant/myorg-assistant:fcf79bf
matching the Deployment, added gitea-registry imagePullSecrets, and set
imagePullPolicy: Always for consistency.
