Enhance SEO and accessibility

[barbaraperic]

Changes

1. Added essential SEO elements:
   • Meta description
   • robots.txt file
   • sitemap.xml file
2. Improved accessibility by enhancing image alt attributes in Footer and Header components

Purpose

These changes aim to improve the website's search engine visibility and make it more accessible to users relying on screen readers or other assistive technologies.

Testing

Verify:
• The sitemap.xml is properly generated and accessible
• robots.txt is correctly configured
• Image alt texts are meaningful and descriptive in Footer and Header components
• Meta descriptions appear correctly in page source

Note

I added a slight refactor in the Header component so that the elements are grouped together and aligned with the main content.

@ianconsolata tagging for visibility :)

shouldn't this be "Disallow: /" for vote.storswift.io (as the dev site) and only "Allow: /" on vote.fil.org ?

Also shouldn't the sitemap change similarly?

Ah thank you, didn't realised there were 2 different deployments. Looking at the code, I believe that vote.fil.org is a test environment and vote.storeswift is the production? href={network === 'testnet' ? "https://vote.fil.org/" : "https://vote.storswift.io/"}

So we should have something like this?

User-agent: *
Disallow: /api/
Disallow: /power_voting/api/
Allow: /

Disallow: https://vote.fil.org/
Sitemap: https://vote.storswift.io/sitemap.xml

vote.fil.org should be production. @ianconsolata, unless I'm insane?
