Event call sites (product_view, add_to_cart, checkout_start, purchase) were only passing visitor_hash and pathname, leaving browser, OS, screen size and country nil. Add AnalyticsHook.attrs/1 helper to extract common analytics fields from socket assigns, and use it in all LiveView event call sites. Checkout controller reads the same fields from the session. Also fix plug analytics test to clear stale events before assertions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
