Refactor network device management and SSH terminal integration

- Removed the old NetworkDeviceManager class and replaced it with a new NetworkDeviceProvider class to streamline network device handling.
- Updated various widgets (NetworkDevicesToConnectWidget, NetworkDevicesWidget, SSHTerminalTool) to utilize the new NetworkDeviceProvider for device management.
- Introduced a new SSHTerminalTool class to manage SSH connections, replacing the OpenSSHTerminalWidget.
- Enhanced device selection UI to support both wired and wireless devices, including manual IP connection options.
- Improved signal-slot connections for device addition and removal events.
- Cleaned up unnecessary includes and code related to the old SSH terminal widget.
- Added checks for device jailbreak status during SSH connection attempts.
