Subject: feat: integrate schema.org support and enhance component structure

- Added schema.org support by introducing `schema-dts` for structured data in components.
- Updated `Head`, `BaseLayout`, and various page components to accept and utilize schema props for better SEO.
- Created new utility schemas for blog posts and website to standardize structured data implementation.
- Enhanced the `SocialLinks` section by utilizing dedicated icon components for improved maintainability.
- Refactored the `Header` component to improve accessibility and structure.
- Introduced new icons for social links and integrated them into the layout.
