Introduce ModernProgressBar, a custom control with gradient fill, rounded corners, indeterminate animation, and optional status text. Integrated AdvancedSharpAdbClient to provide real-time progress updates for APK installs and OBB copies, updating the UI to reflect the current operation and its progress. Refactored ADB methods to support async progress reporting, updated MainForm to use the new progress bar features, improved user feedback with clearer confirmation messages during and after sideloading, added a new icon based on the VRP server icon and enabled it in the window title bar.
