Add Geocodio as a sponsor for The Vibes

[simonhamp]

Summary

• Adds Geocodio to the Sponsored By grid on the /the-vibes page
• Adds a new <x-sponsors.logos.geocodio> Blade component containing the brand wordmark SVG (uses brand red #E62B28 so it works on both light and dark backgrounds)
• Link points to https://www.geocod.io/ with nativephp / thevibes UTM tags

Test plan

• Visit /the-vibes, scroll to "Sponsored By" — Geocodio logo card renders alongside the other sponsors
• Verify the logo looks correct in both light and dark mode
• Click the card and confirm it opens the Geocodio site with the expected UTM parameters
