feat(seeder): add ticket products to test events

- Added migration to optimize OnTicket images using OptimizeOnticketImagesSeeder.
- Updated OnTicketTenantSeeder to reference optimized image formats (AVIF).
- Modified OnticketImmersiveHeroCarouselSeeder to use AVIF images for hero carousel.
- Created OptimizeOnticketImagesSeeder to replace existing attachments with optimized images.
- Adjusted TestEventsSeeder to utilize AVIF images for events.
- Updated tests to verify the correct image formats and ensure optimized images are stored.
- Added new image files in AVIF format for logos, backgrounds, and event images.

 # Project Conventions
 
+## Test database safety
+
+- Tests must use SQLite `:memory:` through `tests/bootstrap.php` and `Tests\TestCase`.
+- Never run tests, `migrate:fresh`, `migrate:refresh`, or `db:wipe` against a persistent database, including the developer's `shopit` database.
+- Never bypass the connection safety guard to resolve test failures. Use `php tests/verify-database-safety.php` to verify isolation without queries or migrations.

 ## Notes For Future Changes
 
 - New features should be added inside the corresponding domain first.
-- If a concern does not belong to an existing domain, create a new domain under `app/Domains`.
+- Add new business features to the appropriate area under `app/Domains`.
+- Keep generic reusable code in `app/Shared`; do not use it as a catch-all for

 - Avoid placing new business code in `app/Http/Controllers` or `app/Models`.

+- `Cart`: pertenece a un tenant y opcionalmente a un usuario; calcula el total, permite agregar, actualizar o quitar ítems y apunta a su reserva de stock vigente mediante `current_stock_reservation_id`.
 - `CartItem`: referencia un `CatalogItem` y, opcionalmente, una `Variant`; sólo persiste la selección y cantidad, y expone siempre los datos vigentes del catálogo.
 
 ## Servicios
 
 - `CartService`: obtiene el carrito, modifica ítems y administra la cookie del token invitado.
-- `ExpireCartReservationsService`: libera las reservas vencidas de carritos activos y elimina los carritos que quedan vacíos.
 - `GuestCartMergeService`: incorpora el carrito invitado al usuario cuando este se autentica.

 Un carrito puede pasar a `checkout`. Las compras directas usan un carrito técnico con `origin=direct_checkout`; los carritos normales conservan `origin=user` y pueden restaurarse al cancelar o vencer la compra.
 
-El comando unificado `php artisan reservations:expire` procesa primero las compras vencidas y luego las reservas activas sin compra cuyo `expires_at` haya vencido. Se ejecuta cada minuto mediante el scheduler, conserva la fila de reserva con estado `expired`, elimina el ítem abandonado y elimina lógicamente el carrito cuando queda vacío. Cada intento registra sus resultados o su error en el log diario `storage/logs/commands/commands-AAAA-MM-DD.log`.
+Cada edición sincroniza una única reserva para el carrito completo. Si varios ítems o bundles consumen el mismo inventario, se persiste una sola línea con la cantidad agregada. Al editar durante checkout, la compra anterior queda `superseded`, se desvincula y el carrito conserva la misma reserva activa con sus líneas actualizadas.
+
+El comando unificado `php artisan reservations:expire` recorre una sola vez las reservas activas cuyo `expires_at` haya vencido. Cuando pertenecen a un carrito, conserva la reserva y sus líneas como historial, libera el stock como conjunto y cambia el carrito asociado a `expired` sin eliminar sus ítems. Al volver a resolver ese carrito desde la API, el anterior pasa automáticamente a `abandoned` y se crea uno activo y vacío para la misma identidad. El cliente nunca necesita reiniciarlo explícitamente. La API también materializa este vencimiento al acceder al carrito aunque el comando programado todavía no haya corrido.
