docs(loyalty): record session pause + next-session resume sequence

re-apply post-reset, program sanity check, live log tail + fresh
enrollment).

+Session paused 2026-05-16 evening. To resume Test 1 round 2:

+1. Re-apply SMTP overrides under `/admin/settings` (port 587, STARTTLS, `support@wizard.lu`) — the reset wiped them.
+2. Confirm `/admin/loyalty/programs` shows the Fashion Group program (should be seeded by `seed_demo.py`).
+3. Tail `api` and `celery-worker` logs live, then enroll at `https://fashionhub.rewardflow.lu/loyalty/join` with a fresh email. The point of the live tail is to catch where B1-F actually dies — at dispatch, at SMTP, or somewhere else.
