Adds a systemd-timed worker that nudges customers who paid but never completed
their intake form (which stalls fulfillment).
- migration 087: intake_reminder_count + intake_reminder_last_at on
compliance_orders (makes the daily run idempotent and bounded), plus a
partial index for the paid-order eligibility scan.
- scripts/workers/intake_reminder.py: each run emails any paid order with
intake_data_validated != TRUE, capped at 10 reminders/order, at most one
consolidated email per customer per day (groups a customer's incomplete
services into one email). Reuses the post-payment intake URL format
(/order/{slug}?order={n}) and the API's email validation, skipping
placeholder/invalid addresses (synthetic@, pipeline.com, etc.). Sends via
smtplib with SMTP_PASS (verified working in the worker container).
- worker-crons: pw-intake-reminder timer, daily ~noon ET (16:00 UTC).
