Problem
Manual runs already reject unresolved declared secrets before creating a run, but enabling a schedule does not perform the same preflight. A scheduled worker can therefore begin firing with a terminal configuration error.
Follow-up scope
- Reuse the existing required-secret resolver when creating or enabling a schedule.
- Return a structured 422 response listing missing secret names and connection requirements.
- Preserve existing schedules when editing unrelated worker fields.
- Add API and dashboard coverage for the blocker.
Context
Issue #2255 adds forward error-code instrumentation and an automatic circuit breaker after three consecutive scheduled terminal configuration failures. This issue moves detection earlier without expanding that focused fix.
