			Deep-link receiver for the OIDC Authorization Code + PKCE flow.
			After the user authenticates in the system browser, the OP
			redirects to android://postit-signin?... and Android forwards
			the Intent to the MainActivity (configured SingleTask so the
			existing instance receives OnNewIntent rather than spawning a
			new one).

			The host value (postit-signin) MUST match the
			AndroidRedirectUri constant in PostIt/Settings/Settings.cs and
			the corresponding RedirectUri registered for the 'postit'
			client in IdentityServer (Yavsc.Org ConfigurationDb).
