[Feature request] Allow to deeplink with pre-selected Hub/Device

Allow to activate IoT Explorer with `activation params` in a deep-link to pre-configure the selected Hub, assuming we can use AAD auth, and or/device to navigate to the proper view.

Eg:
`iotex://myhub.devices.net` should open IoT Explorer, login with AAD auth, find the hub and navigate to the devices list view
Show an error message if the desired hub is not available in the default subscription and allow to select a different sub.

To navigate to the device view: `iotex://myhub.devices.net/?deviceId=mydevice
If the device is not found, show an error message and fallback to the device list view

Start by locating the application's deep-link activation entry point and the existing AAD authentication flow. Implement hub and optional device selection, subscription fallback, and the specified error messages, then verify that missing devices return to the device list view.
