This pull request includes changes to the lib/presentation/challenges/widgets/badge_item.dart file to improve the consistency and theming of the badge display components. The most important changes involve replacing hardcoded colors with colors from the ColorScheme provided by the app's theme.

Improvements to theming:

• BadgeIcon class: Replaced hardcoded colors with colorScheme.outline and colorScheme.onSurfaceVariant for better theme consistency.
• BadgeDetailsSection class: Updated text colors to use colorScheme.onSurface and colorScheme.onSurfaceVariant instead of hardcoded colors.
• BadgeProgressSection class: Used colorScheme.surfaceContainerHighest and colorScheme.onSurfaceVariant for the progress bar and text colors. [1] [2]
• BadgeAchievementDate class: Changed icon and text colors to use colorScheme.primary and colorScheme.onSurfaceVariant for achieved badges. [1] [2]
