Add Toast in the newsletter on subscribe

[akofficial10]

Fixes #533

What’s New

• Added a toast notification to the newsletter subscription form in the footer.
• Toast displays a success message (Successfully Subscribed!) when a user subscribes.
• Auto-hides after 3 seconds, with manual close option.
• Ensured toast styling is consistent with the design (solid white background, subtle shadow, green accent).

Why

Improves UX by giving users immediate feedback on successful newsletter subscription.

Changes

• Updated FooterLayout.tsx to handle toast state (showToast).
• Integrated toast rendering directly in the newsletter section.
• Added new CSS styles (.newsletter-toast, .toast-content, etc.) for proper positioning and styling.

Testing

• Subscribed via footer form → toast appears ✅
• Toast disappears automatically after 3s ✅
• Close button hides toast instantly ✅
• Works across mobile and desktop ✅
