Fixed new user modal pre-populating with first name and last name of acting user

[snipe]

Because Laravel assumes $user is the logged in user if one has not beed explicitly passed, the new user modal would pre-populate some information from the admin trying to create them.

This also adds some tests around that so we can make sure future Laravel upgrades do not change the expected outcome.

PR Summary

• Improved Modal Display Formatting
  We updated the method in which the system displays modals to make them more structured and readable to users. This has led to a smoother interaction experience with dialog boxes.

• Enhanced Form Initialization
  We made changes to the name input fields in our user forms to retain input values even after resetting, which allows for less repetition and more efficient interaction with our system.

• Optimized Default Input Handling
  We tweaked the handling of default input in the user name fields, so the system can better process potential user inputs.

• Expanded Security Checks in Test Cases
  We've improved the security in modal views by ensuring user data (such as first and last names and email) is not visible. The enhanced testing guarantees that user privacy is sustained, making our software safer to use.

Pulled this down and tried it on the checkout asset screen. Looks good to me.
