Closes #246
Description
This PR implements a centralized, lightweight toast notification system across the Next.js frontend application. By utilizing React Context and a custom state provider, the system enables components throughout the tree to trigger consistent, accessible, and non-blocking notification alerts (success, error, warning, info) without prop drilling.
Changes
Core Architecture
ToastProvider: A global context wrapper added to the root layout (app/layout.tsx or _app.tsx) that manages an array of active toast instances.
useToast Hook: A custom React hook exposing a simple API (toast.success('Message'), toast.error('Message'), etc.) for consumer components.
ToastContainer & Toast Components: Fully responsive, animated UI components positioned in a fixed overlay (e.g., top-right). Styled with Tailwind CSS to match the PropChain design language.
Features Implemented
Multi-Type Support: Distinct visual states, iconography, and semantic coloring for success, error, warning, and info types.
Auto-Dismiss Lifecycle: Integrated a countdown manager using setTimeout within each toast instance to automatically remove itself after a set duration (default: 4000ms), safely clearing memory references.
Manual Close: Included an explicit dismiss button (X) on every alert instance for immediate manual closure.
Acceptance Criteria Verification
[x] Toasts display correctly across pages: Verified fixed position overlay overlays cleanly over nested page layouts without interfering with z-index hierarchies.
[x] Notifications auto-close properly: Active timeouts trigger exit cleanup smoothly without lingering DOM nodes or memory leaks.
[x] Reusable implementation: Fully encapsulated inside a custom hook, standardizing notification dispatches system-wide.
Testing & Quality Assurance
Component Coverage
[ ] Test firing multiple toasts rapidly (Should queue/stack cleanly up to a reasonable viewport layout threshold).
[ ] Test routing to a new page while a toast is active (Should persist or unmount cleanly depending on application requirement; defaults to persistent until timeout).
[ ] Test hovering over an active toast (Optional: Verify if auto-dismiss pauses on hover, if implemented, or continues countdown).
[ ] Test cross-browser responsiveness (Ensuring proper layout shifts on mobile viewports).
