PR Summary

• Enhanced User-Accessory Interaction
  In AccessoryCheckoutController.php, a new feature was added that allows for multiple accessories to be linked to users based on specified quantities. In addition, an event is now initiated each time an attachment occurs which can be useful for tracking and logs.

• Enhanced User-Consumable Interaction
  Similar to the accessories, the ConsumableCheckoutController.php now has a feature for attaching multiple consumables to users depending on the provided quantities. After each attachment, an event is also triggered for easy tracking.

• User Interface Update for Accessories
  An update was made to the accessories directory's checkout.blade.php file. This update includes a new input field that enables users to specify the quantity of accessories they want to check out.

• User Interface Update for Consumables
  Analogous to the accessories update, the consumables directory's checkout.blade.php file now has a new input field. This enables users to determine the quantity of consumables they intend to check out.
