[HaSistrunk]

In progress...

fix #658

• Remove Bootstrap and AdminLTE styles
• Update Datatables.js to version 2.1.6 and jquery 3.7.1
• Pull in Datatables css, but customize to update table cell padding, the sort icon styles for better contrast, and adjust search/select input widths to work with RAC styles.
• Use RAC styles header with dropdown menus instead of side navigation
• Add standard public RAC footer and secondary footer with links to Docs Site Aurora user guide and digital transfer guide
• Use HTML progress element instead of Bootstrap progressbar in transfer table.
• Remove tab interface on /transfers page
• Replace /appraise page transfer details modal with a link in the table to the transfer details page.
• Implement a tablist with associated tablist.js script adapted from the ARIA Authoring Practices Guide .

Style Library update suggestions:

• Different sized badges. We need a bigger one for these kind of status indications
• Different colored badges.? It might be nice to have a standard green, red, and yellow to use.
• Add btn--xs for buttons in a table (just less padding, don't make font smaller)
