Use blade component for submit redirect on asset edit/create

[snipe]

This builds off the great work @Godmartinz did with the checkout/checkin options and extends it out to creating/editing assets as well.

I switched those redirects to ->to() and returning the route instead of doing the redirect right in the helper, since that makes it more flexible with confirmation messages. I also used slightly friendlier names for the types of things we can redirect to, so I don't have to remember what 0, 1, and 2 are :)

Thanks very much for your help with this, @uberbrady!

PR Summary

• Enhanced Code Readability in 'Helper' Class
  This PR adds 'return' statements to various switch cases within the getRedirectOption method of the Helper class. This change simplifies the readability of the code as routes are now directly returned instead of redirect responses.

• Optimized Session Storage in Controller Classes
  There have been modifications in the way redirect options and checkout types are stored in session in store methods across AssetCheckinController, AssetCheckoutController, and AssetsController classes. The assignment operations in these controller classes have been replaced with the more efficient session()->put() function, enhancing security and performance.

• File Structure Management and Material Reassignment
  A new file named redirect_submit_options.blade.php has been created in the resources/views/blade directory ensuring better file management. Meanwhile, the older redirect_submit_options.blade.php file from resources/views/partials/forms directory has been removed.

• Layout Changes in Several Views
  The views checkout.blade.php and edit.blade.php have been enhanced by adding the x-redirect_submit_options component. The redundant redirect_submit_options include statement has also been removed from edit-form.blade.php layout.

• Test Modification for Better Accuracy
  The getRedirectOptionMethod within the HelperTest class has been updated to use string values instead of numeric values for the redirect_option parameter to improve test accuracy.

Note: Any minor changes related to code formatting and indentation that do not have an impact on code logic have not been elaborated in this summary.
