fix: update search results text colors for dark mode compatibility (#24)

- Changed title text to use .primaryText instead of generic .bodyText
- Changed content text to use .secondaryText for better hierarchy
- Removed redundant .foregroundColor modifier on parent VStack
- Ensures consistent text visibility in both light and dark modes
