fix: add try-catch on agents.invoke and http.fetch in scheduled jobs

- stale-case-reminder: wrap http.fetch in try-catch so network errors
  log and return instead of crashing the job silently
- weekly-feedback-analysis: wrap agents.invoke in try-catch so CEO
  unavailability logs and returns instead of crashing the job
