[TASK] Get rid of the icons library

[yurixander]

Consider getting rid of the icons library, where we have manually created an icon per file, with the SVG path inside. Instead of this, we could use pre-existing and popular libraries, such as React icons or as Drew suggested: heroicons along with web3icons.

• Determine whether it is a good idea to get rid of the icons library, and whether it is too time consuming to refactor the codebase where icons are already used
• Introduce the new libraries, and start to gradually change icons one by one throughout the projects
• Remove the icons library
