Marc Rejohn Castillano 758869920c Fix push notifications never delivered — 3 root causes ... 1. CRITICAL: Double idempotency check silently discarded every notification. process_scheduled_notifications called try_mark_notification_pushed first, then send_fcm called it again and saw "already pushed" → skipped FCM send. Fix: Remove the check from process_scheduled_notifications; send_fcm's own check is sufficient (and needed for direct Flutter client calls). 2. SEND_FCM_URL env var crash: If not configured, edge function crashed on module load. Fix: Derive from SUPABASE_URL (always auto-set) as fallback. 3. Timing windows too narrow: ±30s windows with 60s cron intervals could miss events between runs. Fix: Widen to ±90s. ON CONFLICT DO NOTHING prevents duplicates, making wider windows safe.
