#233

Short Description and Why It's Useful

• Improved the logic of router.beforeEach.
• The router.beforeEach function checks if the user has permission to access a route. If not, it shows a toast message and redirects the user based on the previous route. If the previous route was the login page or the root path, the user is redirected to the settings page; otherwise, they are redirected back to the previous route
