This commit finally adds the dynamically rendered form that changes according to how the user builds their form.
It also fragments the header and footer for the main page into their own separate files for ease of access later.
Vacancy status has also been added to the Vacancies in DB.
All staff application endpoints have also been moved to under the user application endpoints group, for ease of use (duplicated route group).
This commit also includes Chart.js for the whole project using Webpack. It also updates NPM packages to support ChartJS, and suppresses locale.js warnings from Webpack builds.
Gitignore removes the webpack bundle file since that file should be built each time dependencies/js code are modified.
