Added ability to sort on qty and remaining for consumables

[snipe]

I'm always a little loathe to add anything raw as it can often times clash with non-mysql databases, but since mysql is the one we officially support, I guess this is worth doing for the functionality it brings.

PR Summary

• New functionality added to ConsumablesController.php
  A new feature was implemented into the 'ConsumablesController'. Specifically, this was designed to process a condition termed 'remaining' within the index function. Additionally, a new command to facilitate the ordering process, known as "OrderRemaining", was included in the "Consumable" model.

• Change in Attributes of ConsumablePresenter.php
  We tweaked certain attributes within 'ConsumablePresenter.php'. For the columns named 'qty' and 'remaining', they were initially not sortable (as denoted by 'false'). Now, modifications have been made to enable sorting for these columns (changed to 'true').
