refactor(icons): add categoryIcon support for representative category icons

- add optional `categoryIcon` flag to icon metadata helper in add-remove.js and business.js
- mark Add01Icon and ChartLineData01Icon as category representative icons
- use categoryIcon flag in IconsPage to display the most representative icon per category
- add `cursor-pointer` to category sidebar buttons and widen sidebar from 200px to 250px
