Fix bugs and improve UI for Amazon Clone

[Copilot]

App crashed when Supabase env vars were missing. ESLint had 6 errors. Currency symbols were inconsistent. Buy Now button was non-functional. UI lacked polish.

Bug Fixes

• Supabase graceful fallback - Mock client when env vars missing, prevents crash

  const createMockClient = (): SupabaseClient<Database> => {
    console.warn('[Supabase] Environment variables not configured...');
    return {
      auth: {
        getSession: () => Promise.resolve({ data: { session: null }, error: null }),
        // ... minimal mock implementation
      },
    } as unknown as SupabaseClient<Database>;
  };

• ESLint errors - Fixed empty interfaces (type vs interface), require() → ES import, removed any types
• Currency consistency - Wishlist page now uses ₹ like rest of app
• Buy Now functional - Adds to cart and navigates to checkout

UI Improvements

• Hero carousel - Auto-slide (5s), pause on hover, slide indicators, smoother transitions
• Header - Scroll shadow effect, improved hover states, added "Today's Deals"
• Footer - Social icons as buttons, contact info, back-to-top button
• Category cards - Lift animation on hover, arrow on "Shop now"
• Back to top - Floating button appears after 400px scroll
