feat: tweak a few icons & add line editor button to side panel

[dwelle]

• layer icons

  From feedback it's hard for people to intuitively recognize what each layer/z-index button does, so switching to arrows for clarity:

  

• highlighted items

  Changed promo/highlighted items/badges color from pink to primary, and added bold weight

  

• added line editor button to element panel

  

• changed sign-in/up button and added :hover/:active styles for item icons of the WelcomeScreen
