Subject: [PATCH] chore: enhance mobile E2E workflow for iOS simulator
 verification (#1532)

- Added checks for simctl availability and ensured necessary simulator directories exist.
- Improved app installation verification with graceful error handling and fallback checks.
- Enhanced Maestro test execution with detailed output handling and cleanup error suppression.
- Verified the existence of the Maestro test file before execution to prevent failures.
