fix: update footer layout and styles to match dotcom

[jbatesuk]

Summary

Updates the documentation site footer layout and styles to align with the main civo.com website footer.

• Fix protocol and alignment issues with footer elements
• Smooth out hover transitions on footer links
• Remove unused legacy footer configuration in favour of the custom footer component

Footer component

The custom footer (src/theme/Footer/index.js) now manages all footer content — columns, social links, legal links, and copyright — directly via data arrays and extracted components:

const footerColumns = [
  {
    title: 'Company',
    links: [
      { label: 'About', href: 'https://www.civo.com/about' },
      { label: 'Pricing', href: 'https://www.civo.com/pricing' },
      // ...
    ],
  },
  // ...
];

const socialLinks = [
  { label: 'Instagram', href: 'https://www.instagram.com/civocloud/' },
  { label: 'LinkedIn', href: 'https://www.linkedin.com/company/civocloud' },
  // ...
];

const legalLinks = [
  { label: 'Legal', href: 'https://www.civo.com/legal' },
  { label: 'Terms and Conditions', href: 'https://www.civo.com/legal/terms' },
  // ...
];

Social icons are inlined SVGs using currentColor, rendered inside flex circles with hover transitions:

<div className="custom-footer__social">
  {socialLinks.map((social) => (
    <a key={social.label} href={social.href} aria-label={social.label}>
      <div className="footer-circle">
        {socialIcons[social.label]}
      </div>
    </a>
  ))}
</div>

The docusaurus.config.js footer config is now just footer: {} since the custom component handles everything.

Test plan

• pnpm build passes with no errors
• Footer visually matches the dotcom website footer
• Hover transitions on footer links are smooth
• Social icons and logo are correctly aligned

The footer is very large, I know it contains a lot of inofrmations but takes a whole page, are we sure this is what we want?

Hey @fulviodenza - yes its to be consistent with our new sitewide footer - if you look at the site you'll see its the same ;)

[fulviodenza]
