Added the sonner library for toast notifications across various components, improving user feedback for actions such as saving settings, syncing rules, and handling errors. Updated the layout to include a Toaster component for consistent notification display. Refactored alert messages in the backups, gre, and filters pages to utilize the new notification system, enhancing overall user experience.
