New Feature: Theme Background Color

Adds a backgroundColor property to both CourierInboxTheme and CourierPreferencesTheme, allowing users to set a custom background color for these views through the theme system.

TypeScript

const theme: CourierInboxTheme = {
  backgroundColor: '#FFFFFF',
  // ...other theme properties
};

Implementation Details

• Android: Passes backgroundColor directly to the native CourierInboxTheme and CourierPreferencesTheme constructors (supported in courier-android 5.3.1)
• iOS: Applies the background color directly on the native UIView since the Courier_iOS SDK theme constructors don't include this property. Respects the current light/dark user interface style.

• src/models/CourierPreferencesTheme.tsx — Added backgroundColor?: string
• ios/CourierInboxReactNativeManager.swift — Apply background color on the view
