Stage 4 of the page builder: all shop pages now render via
PageRenderer instead of inline templates or PageTemplates.
- Collection: full filter bar moved to renderer (category pills,
sort dropdown, CollectionFilters hook, empty state)
- PDP: related_products and reviews loaded via block data loaders
instead of manual queries
- Cart: page definition loaded in mount, subtotal computed in render
- Search: page definition loaded in mount, handle_params unchanged
- Added Phoenix.VerifiedRoutes to PageRenderer for ~p sigil
- Net -55 lines (128 added, 183 removed)

Every key shop flow now works via plain HTML forms when JS is
unavailable. LiveView progressively enhances when JS connects.
- PDP: form wraps variant/qty/add-to-cart with action="/cart/add"
- Cart page: qty +/- and remove use form POST fallbacks
- Cart/search header icons are now links with phx-click enhancement
- Collection sort form has GET action + noscript submit button
- New /search page with form-based search for no-JS users
- CartController gains add/remove/update_item POST actions
- CartHook gains update_quantity_form and remove_item_form handlers
- Fix flaky analytics tests caused by event table pollution
