CronJobs were referencing 'myorg-assistant:latest' (a local image that
doesn't exist in the cluster), causing ImagePullBackOff on all 4 active
CronJob pods. Updated all 5 CronJob manifests to use the same image as
the Deployment (git.rogi.casa/roger/myorg-assistant/myorg-assistant:fcf79bf)
and added imagePullSecrets: gitea-registry for authentication.
