Apply colors from the palette to poll views

#656 (comment)

🎯 Goal

Poll views in SwiftUI implementation don't have all the palette colors applied properly to them. Namely "Create Poll", "Poll Results" don't have background color, it's just black. And poll cells, don't have text colors for different user messages applied.

🛠 Implementation

I just added corresponding colors from the @Injected(\.colors) var colors

🧪 Testing

Try creating a poll with custom color scheme applied to that chat with default cells.
