 * Shared admin bell row when the cron detects a customer's subscription has
 * passed its period end. Two states mirror the customer-facing event:
 *
 *   - 'grace'   : within Setting('grace_period') days of period_end, still ACTIVE
 *   - 'expired' : suspended this cron tick (status set to ENDED)
 *
 * Audience is `admins` so the row is shared (1 INSERT, every admin sees it).
 * The group_key is keyed by subscription uid + state so repeat ticks dedupe and
 * a state transition produces a fresh row.
