Update Open SaaS meta tags and Hero description (#476)

* Update Open SaaS meta tags and Hero description

Enhanced Open Graph and Twitter meta tags to include 'Built by Wasp' in the description. Updated the Hero section description to clarify the project as a starter kit and added attribution to Wasp with a link.

* Update links and branding to use WaspUrl and improve accuracy

Replaced hardcoded Wasp URLs with the new WaspUrl constant across landing page components and content sections. Updated meta tags and branding language from 'Built by' to 'Powered by' Wasp. Adjusted company links to use the correct license and Wasp team attribution. Added WaspUrl to shared constants for consistent usage.
