implement ServiceManager to handle services safely & cleanup UI

- Added `install_ipa.cpp` to handle IPA installation on iOS devices using the installation proxy.
- Introduced `ServiceManager` class to centralize and thread-safely manage device service operations, including AFC file operations.
- Updated `DeviceInfoWidget` layout for improved UI responsiveness.
- Refactored `GalleryWidget`, `MediaStreamer`, `PhotoExportManager`, and `PhotoModel` to utilize `ServiceManager` for safer AFC operations.
- Enhanced error handling and logging across various components.
- Adjusted `ToolboxWidget` to streamline device change handling and UI updates.
