Subject: refactor: update schema handling and improve SEO metadata

- Changed schema type from WithContext<Thing> to Thing[] in Head, BaseLayout, and JsonLd components for better flexibility.
- Added optional robots meta tag to Head component.
- Updated JSON-LD generation in JsonLd component to include a structured payload.
- Enhanced page and blog schemas to support breadcrumb and person schemas for improved SEO.
- Introduced new utility schemas for website and person to streamline schema generation.
- Refactored existing schemas to align with the new structure and ensure consistency across components.
