Each category & command have its own color & icon

[AerunDev]

As a User
I would like my event commands and their categories to have their own colors & icons
So that I can easily recognize them

Acceptance criteria

• A design for each category header of the command library is made on Figma and referenced in this issue
• Some propositions are made about an icon library (like G Icons) until our icons are created for each command (which can take a looooong time)

Tip

If necessary, we can use the command category icon for a first version.
