feat: implement splash screen handling in navigation and interactions

- Added a new function `waitForSplashScreenToDisappear` to manage splash screen visibility, ensuring it does not block user interactions.
- Integrated splash screen checks in various navigation functions and interaction methods to enhance user experience by waiting for the splash screen to disappear before proceeding.
- Updated test setup to disable the splash screen during tests for consistent testing behavior.
