Open more info on its own page to allow companion apps to open a specific entity or let a user load a specific entity

We were having a discussion over in #devs_frontend about the more info pop-up and how to best trigger it:

The android app has a new beta feature that integrates with Android 11 Power Menu, this allows us to assign entities to tiles to let the user quickly control a device without opening the app. A long press on this icon will take the user to their default page but it would be ideal to display the more info dialog to the user.

The second screenshot in the above link shows a black page which is a bug that was just fixed however we are still just loading the home page and would ideally show just the more info dialog.

Ideally if we can have something like https://mydomain.com:8123/lovelace?entity_id=sensor.test would load just the more info dialog for which ever entity gets sent.

This is the starting recommendation:
https://discord.com/channels/330944238910963714/351047592588869643/768591750226116629

This would really help complete the look and allow this page to always show the most up to date content that the frontend team builds. Also I am sure others may find it useful as well to directly link to this page from say an actionable notification.

Just an update on this but in home-assistant/android#1446 we are now triggering the pop-up using some JS mentioned in the links above

Looks like after 2021.6 the code used above is no longer working in the android app

Just a heads up, in Android 12, Google changes the way Device Controls works as seen here https://www.androidpolice.com/2021/06/09/android-12-beta-2-gets-new-shortcuts-for-wallet-and-device-controls/
It's completely moved away from the power menu and is not as easy to use as in Andriod 11.

Although they may have changed how you access it the feature request is independent of the power menu. Users can trigger the more info pop-up in notifications and even Android shortcuts. Just about anywhere our webview implementation can be accessed.
