[Frontend] Fix `externaltools/page.tsx` — Verify and Apply Standard Background

[Olowodarey]

Area: frontend/src/app/externaltools/page.tsx

Description:
The externaltools page uses bg-[#0a0a0a] — the same flat near-black as the terms page — instead of the standard PageBackground. This page should match the rest of the platform visually.

Tasks:

• Open frontend/src/app/externaltools/page.tsx and check the current root background class
• Import PageBackground from @/component/PageBackground
• Replace the root background div with <PageBackground>
• Ensure <Header /> and <Footer /> are present
• Verify all existing content on the page still renders correctly
• Test on mobile and desktop

Acceptance Criteria:

• Page background matches the homepage gradient + network lines
• All existing page content renders correctly
• No TypeScript errors
