/**
 * Creates a navigation handler that supports keyboard, modifier clicks, and middle mouse button.
 *
 * This is a curried function that takes a URL and router, and returns an event handler that:
 * - Handles keyboard navigation (Enter/Space keys)
 * - Opens in new tab on Cmd/Ctrl + click
 * - Opens in new tab on middle mouse button click
 * - Performs normal navigation on regular click
 *
 * @param url - The relative URL to navigate to (e.g., "/project/123/functions/my-function")
 * @param router - Next.js router instance (supports both Pages Router and App Router)
 * @returns Event handler function for onClick, onAuxClick, and onKeyDown
 *
 * @example
 * ```tsx
 * const router = useRouter()
 * const handleNavigation = createNavigationHandler(`/project/${ref}/functions/${slug}`, router)
 *
 * <TableRow
 *   onClick={handleNavigation}
 *   onAuxClick={handleNavigation}
 *   onKeyDown={handleNavigation}
 *   tabIndex={0}
 * />
 * ```
