Disable checkout when Stripe isn't connected (cart drawer, cart page,
and early guard in checkout controller to prevent orphaned orders).
Show amber warning on order detail when email isn't configured.
Fix pre-existing missing vertical spacing between page blocks.

When a Stripe checkout session expires without payment, if the customer
entered their email, we record an AbandonedCart and schedule a single
plain-text recovery email (1h delay via Oban).
Privacy design:
- feature is off by default; shop owner opts in via admin settings
- only contacts customers who entered their email at Stripe checkout
- single email, never more (emailed_at timestamp gate)
- suppression list blocks repeat contact; one-click unsubscribe via
signed token (/unsubscribe/:token)
- records pruned after 30 days (nightly Oban cron)
- no tracking pixels, no redirected links, no HTML
Legal notes:
- custom_text added to Stripe session footer when recovery is on
- UK PECR soft opt-in; EU legitimate interests both satisfied by this design
Files:
- migration: abandoned_carts + email_suppressions tables
- schemas: AbandonedCart, EmailSuppression
- context: Orders.create_abandoned_cart, check_suppression, add_suppression,
has_recent_paid_order?, get_abandoned_cart_by_session, mark_abandoned_cart_emailed
- workers: AbandonedCartEmailWorker (checkout queue), AbandonedCartPruneWorker (cron)
- notifier: OrderNotifier.deliver_cart_recovery/3
- webhook: extended checkout.session.expired handler
- controller: UnsubscribeController, admin settings toggle
- tests: 28 new tests across context, workers, and controller

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.

Three-layer pipeline: Plug for all HTTP requests (no JS needed), LiveView
hook for SPA navigations, JS hook for screen width. ETS-backed buffer
batches writes to SQLite every 10s. Daily-rotating salt for visitor hashing.
Includes admin dashboard with date ranges, visitor trends, top pages,
sources, devices, and e-commerce conversion funnel. Oban cron for 12-month
data retention.
