Footer "Account" links are broken — My Cart, Checkout, Order pages missing

[thomasiverson]

Description

All links in the footer "Account" section are placeholder # links that don't navigate anywhere:

• My Cart → #
• Checkout → #
• Shopping Details → #
• Order → #
• Help Center → #

Clicking any of these links scrolls the page to the top but does not navigate to a corresponding page. No routes or components exist for these pages.

Expected behavior

Each footer link should either:

1. Navigate to an implemented page with relevant content, or
2. Be removed/hidden until the corresponding feature is built

Steps to reproduce

1. Start the frontend dev server (npm run dev:frontend)
2. Navigate to http://localhost:5137
3. Scroll down to the footer
4. Click any link under the "Account" heading
5. Observe that the page scrolls to the top but no content is displayed

Affected area

• frontend/src/components/Footer.tsx — contains the placeholder links
• frontend/src/App.tsx — missing route definitions for these pages
