[BUG]: Footer "Terms of Service" and "Privacy Policy" links redirect to home page

### Bug Description

The footer includes links to /terms (Terms of Service) and /privacy
(Privacy Policy). Neither route is registered in the router, so navigating
to either one silently falls through to the catch-all route and redirects
to the home page, instead of showing an error or the actual page.

### Steps to Reproduce

1. Go to https://orgexplorer.aossie.org/ (or run locally)
2. Scroll to the footer
3. Click "Terms of Service" or "Privacy Policy"
4. Observe that you're redirected to the home page instead of seeing the
expected content

### Logs and Screenshots

Confirmed in Footer.jsx — the footerLinks array points to /terms and
/privacy, but no matching route exists in the router config; these paths
fall through to the catch-all route.

### Environment Details

- OS: Windows 11
- Browser: Chrome 120
- Node.js: v24.13.0

### Impact

Low - Minor inconvenience

### Code of Conduct

- [x] I have joined the [Discord server](https://discord.gg/hjUhu33uAn) and will post updates there
- [x] I have searched existing issues to avoid duplicates

Open Footer.jsx and the router configuration to verify how /terms and /privacy are declared and how the catch-all handles them. Confirm the intended Terms of Service and Privacy Policy destinations or content, then verify both footer links render those pages rather than redirecting to home.
