Instead of an every-minute poller, each scheduled message gets its own
Cronicle event created at schedule time:
- One-time: year/month/day/hour/minute one-shot
- Daily/weekly/monthly: recurring timing matching the recurrence setting
Retry (PUT with new scheduled_at on failed messages) also creates a new
Cronicle event and resets status to pending. Recurring messages reuse
their existing Cronicle event across occurrences.
