HelpScout redesign

[luisivan]

Idea

• Optimize loading time
• Update border and shadow (design needed cc @dizzypaty)
• Optimize icon
• Update for new HelpScout design specs (new designs) (@AquiGorka)
• Use DiscButton from aragonUI
• Encapsulate opt-out logic into a HelpScout module (e.g. a hook?) cc @sohkai

Design

Figma

Frontend implementation

• @AquiGorka to review current state and spec requirements (Sprint 27):

First iteration

• New designs implementation
  • Review colors
  • Review spacing
  • Review styling
  • Review opt-in flow (not opted in, loading, opted in)
  • Update illustration
  • Update links to Links
• Tech debt
  • Remove border
  • Update to use newstyle question icon
  • Encapsulate opt-out logic into a HelpScout module (currently passing a prop up and down the tree, a context hook may remove that behaviour and encapsulate this logic)

Next iteration
