Admins can now edit pages directly on the live shop by clicking the
pencil icon in the header. A sidebar slides in with block management
controls (add, remove, reorder, edit settings, save, reset, done).
Key features:
- PageEditorHook on_mount with handle_params/event/info hooks
- BlockEditor pure functions extracted from admin editor
- Shared BlockEditorComponents with event_prefix namespacing
- Collapsible sidebar: X closes it, header pencil reopens it
- Backdrop overlay dismisses sidebar on tap
- Conditional admin.css loading for logged-in users
- content_body block now portable (textarea setting + rich text fallback)
13 integration tests, 26 unit tests, 1370 total passing.

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
