v0.2.2

• New: a PDF certificate now shows a "View full report (PDF)" link beneath its preview, so a
  multi-page COA is fully reachable — the preview shows page 1, and the link opens the complete file
  (e.g. a second page with endotoxin / sterility results) in the browser's PDF viewer.
• Change: editors previewing a draft product now see its certificates by default. The public
  still only sees COAs on published products — this just lets a logged-in editor preview a draft
  without extra setup (the default is filterable via coa_vault_published_only_default).
• Change: the Settings page's two storefront-display checkboxes are now a single, clearer 3-way
  choice — automatic placement, manual (shortcode / block), or off. No behaviour change; the same
  underlying options are written, and the previously confusing "off + automatic" dead state is gone.
