fix(myorg-assistant): fix cronjob images - use gitea registry + imagePullSecrets

CronJobs referenced bare 'myorg-assistant:latest' which doesn't exist in
any registry, causing ImagePullBackOff on all 5 CronJobs for 9+ days.
Aligned with deployment.yaml:
  - image: git.rogi.casa/roger/myorg-assistant/myorg-assistant:fcf79bf
  - imagePullPolicy: Always
  - imagePullSecrets: gitea-registry

Affected: deadline-checker, evening-summary, git-sync, morning-briefing, waiting-followup
