Fixed inconsistent attributes order in Print All Assigned report

[FlorentDotMe]

Description

This issue affects the "Print All Assigned" report generated for a user.

There was an error in the field orders of assets and associated assets, resulting on having the default location in the "model" column for the associated assets. I also replicated to assignedAssets the control functions on the field values as applied on assets.

PR Summary

• Improved Error Prevention in Asset Printing
  The code that is responsible for printing assets now checks if the asset's model and category exist before trying to access their properties. This will prevent errors and instead display a message indicating the category or model is invalid when they're missing.

• Date Formatting Enhancement
  The date of the last checkout of an asset is now displayed using a common date formatting function. This change ensures consistency in how dates are displayed in different parts of the system.

• Conditional Signature Image Display
  A check has been added to ensure that a signature image is only displayed if there is indeed a signature logged for the asset. This protects against trying to display non-existent images, which could result in errors.
