Refactor Sidebar Components to Adhere to DRY Principle

[ouhammmourachid]

The current implementation of Sidebar components in the repository appears to contain duplicated code segments, violating the DRY (Don't Repeat Yourself) principle. This redundancy can lead to maintenance issues, increased development time, and potential bugs.

To improve the codebase's maintainability and readability, it's crucial to refactor the Sidebar components to eliminate redundancy and adhere to the DRY principle. This involves identifying duplicated code segments and abstracting them into reusable functions or components.

here is a suggestion, but I am not sure about the name of class
SidebarGroup.tsx

"use client";
import SidebarLinkGroup from "./SidebarLinkGroup";

const SidebarGroup = ({...props}) => {
    const { name,iconPath,elements,path } = props;
    const pathname = usePathname();
    let extractedPath = path.split("/")[1];
    if (extractedPath === "") {
      extractedPath = "dashboard";
    }
    let storedSidebarExpanded = "true";
    const [sidebarExpanded, setSidebarExpanded] = useState(
        storedSidebarExpanded === null ? false : storedSidebarExpanded === "true",
      );
    
    useEffect(() => {
        localStorage.setItem("sidebar-expanded", sidebarExpanded.toString());
        if (sidebarExpanded) {
          document.querySelector("body")?.classList.add("sidebar-expanded");
        } else {
          document.querySelector("body")?.classList.remove("sidebar-expanded");
        }
      }, [sidebarExpanded]);
    
    return (
      <>
      {elements ?
      <SidebarLinkGroup

        pathname === path || pathname.includes(extractedPath)
