Pull Request Overview

This PR enhances the onboarding flow by adding new localized strings, refactoring UI components for better state management, and introducing shared safe‐area utilities.

• Adds localized keys for invitation options and onboarding welcome buttons.
• Refactors HAProgressView to use an ObservableObject view model and centralizes safe‐area insets into a shared SwiftUI extension.
• Enhances OnboardingWelcomeView with animation constants and safe‐area handling, and updates OnboardingServersListView to conditionally show header and manual input buttons after discovery delays.

• [nitpick] The secondaryButton name is generic and may be unclear; consider renaming it to learnMoreButton or learnMore to better reflect that it opens the Learn More/Get Started documentation.

public static var secondaryButton: String { return L10n.tr("Localizable", "onboarding.welcome.secondary_button") }
