fix: correct image paths in documentation markdown files

- Updated all image references in doc/examples/*.md files to include
  example subdirectory names in the path structure
- Changed broken paths from ../../media/examples/filename.png to
  ../../media/examples/{example_name}/filename.png
- This matches the actual directory structure where images are stored
  and fixes GitHub Pages PNG display issues
- Verified documentation builds correctly with make doc
- All 10 documentation files updated with correct image paths

Fixes GitHub Pages PNG display issue completely
