refs #21483 [fid] vufind changes to delete orders

* no security question as of now
* wont work without expansion of fidis
* added route for order deletion (requires admin rights)
* config parameters displayCols defines, 'delete' for the delete button
* using font awesome for the fa-trash symbol, can be overwritte in field-delete.html
* design changes for orderDelete
* Code Stlye changes to Delete Order Modal
** Modal has its own template now, only rendered when activated via config
** fixed a bug where the default fid delete button would have missed crucial info and had just outright deleted the entry
** known problem: the delete route is actually reacheable for any one user but will be rebuffed by fidis itself, still not entirely clean
