feat: redesign page heroes, implement organic markers, and streamline contact flow

- Refined hero sections for About, Blog, Websites, and Case Studies for a bespoke industrial entry point.
- Redesigned Marker component using layered SVG paths for an organic, hand-drawn highlighter effect.
- Restored technical precision in ArchitectureVisualizer with refined line thickness.
- Streamlined contact page by removing generic headers and prioritizing the configurator/gateway.
- Updated technical references to reflect self-hosted Gitea infrastructure.
- Cleaned up unused imports and addressed linting warnings across modified pages.
