This PR implements several performance optimizations for the OnboardingScreen in the Compose Multiplatform application.

Key improvements:

  • Object Allocation Reduction: Defined static RoundedCornerShape constants to avoid repeated allocations during recomposition.
  • Memoization: Applied remember to expensive Modifier chains and Brush objects (gradients) across all onboarding components.
  • Efficiency: Optimized the FuturisticProgressIndicator's rendering loop by hoisting stable assets and replacing redundant gradient calculations with a simpler SolidColor background.

Performance impact:

  • Reduced GC pressure during onboarding transitions.
  • Improved frame stability for progress animations.
  • No changes to visual output or functionality.

Verified with ./gradlew :composeApp:spotlessCheck and ./gradlew :composeApp:jvmTest.

- Extract private top-level shape constants for OnboardingSkipButton, OnboardingMainContent, and ProgressBar.
- Memoize the modifier chain and vertical gradient in onboardingLayoutModifier using remember.
- Use remember for linear and radial brushes in OnboardingIconDisplay.
- Optimize FuturisticProgressIndicator by hoisting the active gradient out of the repeat loop and using SolidColor for the inactive state.

These changes reduce ephemeral object allocations and improve interaction smoothness during the onboarding flow.
