Loading states missing on asynchronous operations

[AdamJ]

Save, delete, and export operations complete silently. The user receives no feedback that work is in progress, outside of a spinning icon in the navigation bar.

ToDo

• Track loading state with useState<boolean>, set to true before the asynchronous call and false in finally. Pass disabled={isLoading} and render a spinner or "Saving..." label inside the button during loading. (potentially use Shadcn's <Button> as it accepts children)
