docs: loyalty go-live update + Hetzner reset fix + sweep nav

- docs/proposals/loyalty-go-live-readiness.md — record the
  2026-05-16 session: 7 bugs found during Test 1 round 1
  (TimestampMixin, CardDetailResponse, storefront i18n triple,
  Makefile, meta_keywords), 6 fixed and deployed with commit
  hashes, B1-F still pending repro on the clean DB.

- docs/deployment/hetzner-server-setup.md — fix section 12
  step 8 to call seed_email_templates_core.py +
  seed_email_templates_loyalty.py instead of the non-existent
  seed_email_templates.py, and add seed_demo.py at the end.
  Append a note about post-reset state (.build-info + admin
  settings).

- mkdocs.yml — sweep 14 previously-unlinked proposals and 2
  module docs (loyalty/production-readiness.md,
  prospecting/batch-scanning.md) into the nav so the strict
  build no longer warns.
