The payment_reminder worker (15min/1day/2day recovery emails) ran daily but sent
0 emails for months because:
1. ORDER_TABLES omitted compliance_orders entirely -- where ALL trucking/renewal/
telecom orders + every abandoned cart actually live. It only checked
canada_crtc/formation/bundle (near-empty). Added compliance_orders.
2. The reminder_15m/1d/2d_sent_at dedup columns didn't exist on compliance_orders
(added via migration).
3. The systemd timer ran once daily (16:00 UTC) -- can't catch the 15min or 1day
windows. Changed to every 30 min.
Verified live: a backdated pending order triggered its 1-day reminder and a real
abandoned cart (Simpson & Co) got a recovery email, both delivered.
