feat(landing): add favicon and improve OG metadata

[Aakriti0207]

Description

This PR improves the landing page social preview experience by completing missing metadata and adding favicon assets.

Changes Made

• Added favicon assets:
  - favicon-32x32.png
  - favicon-180x180.png
• Added favicon links in apps/landing/index.html
• Added missing Open Graph metadata:
  - og:image
  - og:url
• Added Twitter metadata for improved social sharing previews

Closes #49

Type of Change

• feat — new feature
• fix — bug fix
• test — adding or improving tests
• docs — documentation only
• refactor — code restructuring without behaviour change
• perf — performance improvement
• chore — build, CI, or dependency update

Context (DeFi / Stellar)

Field	Value
Network tested on	N/A
Protocol affected	None
Touches contracts?	No
Wallet used	N/A

Testing

Attempted local verification in GitHub Codespaces.

• Verified favicon assets and metadata were added to apps/landing/index.html
• Verified Open Graph and Twitter meta tags were added
• Followed the suggested relative favicon path setup (./favicon-*)

Local testing note

I encountered an issue where the local Codespaces environment consistently redirected to /app, which made it difficult to fully verify favicon rendering for the landing page (apps/landing/) locally. Based on maintainer guidance, the favicon paths were updated to use relative references for compatibility with both local development and deployment.

Feedback or suggestions on local verification are very welcome.

Hey @Aakriti0207, could you enable "Allow edits from maintainers" on this PR? There's a small fix needed in the build script to get the favicons rendering on the deployment and it'll be faster for me to apply it directly.

Thanks for pointing this out! I’ve now re-exported the favicon assets at the correct dimensions (32×32 and 180×180) and optimized/compressed them to significantly reduce file size for better performance.
Now -
file size for 32x32 : 1.23KB
and for 180x180: 31.0KB
Please let me know if further optimisations are needed
