fix(homepage): align index nav/footer with verify.html pattern

[GsCommand]

Motivation

• The homepage nav and footer needed to exactly match the working pattern used by public/verify.html because prior changes left the homepage visually inconsistent.
• The goal was to copy the canonical nav/footer behavior (layout, spacing, Docs dropdown, active state, and grouped footer columns) while leaving hero/body content and other routes untouched.

Description

• Updated only public/index.html to ensure the top navigation uses the verify-style structure/order and the same active-state styling by adding the .nav-links a.active { color: var(--text); background: var(--surface); } rule.
• Replaced the old homepage footer CSS with the footer rules from public/verify.html (3-column grouped layout, spacing, typography, and link styles) to remove cramped/plain styling.
• Adjusted responsive rules so the footer collapses to a single column at smaller breakpoints to match the verify page behavior and removed conflicting legacy footer rules.
• Kept all hero/body content, API routes, schemas, and public/verify.html unchanged and only modified public/index.html as scoped.

Testing

• Ran npm install which completed successfully.
• Ran npm test and all automated tests passed (26 passing).
• Attempted npm run build but the repo does not include a build script (Missing script: "build").
