Implemented optional ordering of resources in FastAPI admin. Code has been added to accept an 'order_by' parameter in the resource route, if present the list of resources will be sorted accordingly. Templates were updated to support this feature by adding a clickable link to each column header for sorting.

The navigation bar 'navbar-toggler' button has been shifted in the layout.html file. Previously, it was located inside the 'navbar navbar-expand-md navbar-light' div, but now it resides just above the 'collapse navbar-collapse' div. This modification enhances the positioning and visibility of the button, potentially improving the user interface.
