Feature/add ecosystem fundio

[sai216]

Description

Adds Fundio to the x402 ecosystem.
This adds a metadata entry for Fundio and references an existing logo so Fundio appears on the ecosystem page.

Files added:

• app/ecosystem/partners-data/fundio/metadata.json
• public/logos/fundio_logo.png

Fundio uses x402 to enable secure, payment-gated donations and content access — a safe payments integration for builders and creators.

Tests

• Manually verified locally:
  • Started site: pnpm dev (from typescript/site) and confirmed dev server runs.
  • Confirmed logo serves at: http://localhost:3000/logos/fundio_logo.png
  • Confirmed metadata JSON exists and is valid.
• No automated tests were required for this metadata-only change.

Checklist

• [x] I have formatted and linted my code (no code changes required; only metadata files)
• [x] All new and existing tests pass (no test changes)
• [ ] My commits are signed (required for merge) -- you may need to rebase if you initially pushed unsigned commits
