chore: import SVG assets instead of using direct paths (#395)

# Remove unused SVG assets and update image references

This PR removes several unused SVG assets from the website and updates image references to use imported assets instead of direct paths:

1. Removed architecture diagram SVG that was no longer needed
2. Removed edge worker logo SVGs (both dark and light versions)
3. Updated image references in PageFrame.astro to use imported assets:
   - Now using imported logo files instead of direct path references
4. Updated Quote.astro component to use imported quote icon:
   - Replaced inline SVG with imported image reference
   - Simplified the component by using an image tag instead of SVG markup

These changes improve maintainability by ensuring assets are properly imported and referenced, while removing unused files to keep the codebase clean.
