Convert Eloquent models to use the new Accessor & Mutator methods

[mikeburg]

Laravel 9 introduced new attribute accessor and mutator methods . The two big advantages are the accessor values are cached, and a single method is only required to define both an accessor and/or mutator.

While there are no plans by the Laravel authors to deprecate the older setNameAttribute() / getNameAttribute() methods anytime soon, the older method is no longer recommended for newer code.

The work invoked is to go through all the files in app/Models folder and convert the models to use the newer methods. The major of the {get,set}NameAttribute functions are fairly simple and consist of a single line.
