Add coverage prettification and sorting functionality

- Introduced `prettify.css` for syntax highlighting in coverage reports.
- Added `prettify.js` to handle code formatting and highlighting.
- Included `sort-arrow-sprite.png` for sort indicators in the coverage table.
- Implemented `sorter.js` to enable sorting and filtering of coverage summary tables.
- Added a search box for filtering table rows based on user input.
