Fixed user assets not updating when a user changes location

[Godmartinz]

Description

I'm not sure how this came to break. but I noticed we are passing a $request value in the asset update instead of the $user->location_id. Assets resync to location updates.

PR Summary

• Change in AssetCheckoutController.php
  The way the system decides where to check an asset out to has been altered. Instead of getting that information directly, it's now determined by a special set of rules defined in a method called determineCheckoutTarget().

• Update in UsersController.php
  When an asset's location requires updating, the system now gets this information from the user's own location details, replacing the previous method where it was coming from incoming request data. This new change ensures the asset's location is more closely tied to where the user is actually located.
