Drift-audit Group 2 (Phase-8 amputation — live wiring, no consumer):
- Recurring tasks never recurred: spawn_recurring_tasks() had no caller.
Register it as a 15-min interval job in the event scheduler (which
app.py already starts/stops). Also add a deleted_at IS NULL guard to
the spawn query in the same change, so a trashed recurring parent can
never resurrect children once the sweep is live.
- Event reminders were stamped reminder_sent_at but never delivered.
_fire_reminders now creates an 'event_reminder' in-app notification
before stamping, so a delivery failure stays retryable. Frontend
NotificationsPanel renders the new type (⏰ + message); message logic
pulled into a notifMessage() helper.
- Remove the dead _fire_push_notif no-op stub (push left in Phase 8) and
its three create_task call sites — no more throwaway tasks per share.
