Refactor: migrate codebase to 'WPF' from 'Worker Service'

[ronnielutaro]

There's a number of limitations that'll potentially hinder future extensibility of the software, among these include, the uncommon practice of developing User Interfaces(UI) for 'Worker Services'. WPF applications have more efficient ways of implementing UI. This is the main reason to refactor the project and migrate it to WPF instead of sticking with Worker Services that may limit extensibility.
