🎯 Goal

Tinting did work when trying to use different tint for navigation bar and the main content

📝 Summary

• Fix tinting for navigation bar which requires using NavigationContainerView and .toolbarThemed()
• Add toolbarThemed(content:) for customised views requiring themed navigation bar
• NOTE! This only works when both navigationBarTintColor and tintColor are customised
