Update SVG logos to use percentage dimensions and add viewBox where missing

- Modified SVG files for logos (webtorrent, wifi, wise-icon, zoom-icon, zoom) to set width and height to 100% for better responsiveness.
- Added viewBox attribute to SVGs that lacked it, using existing width and height values when available.
- Implemented a validation and fixing function in update-data.js to automate the process of ensuring SVGs have the correct attributes.
