Breaking change

Proposed change

This fixes a few issues regarding Sonos media titles since the rework in #33063:

• Use property rather than attribute (unreported issue with Sonos idle #32712)
• Use soco.is_radio_uri to identify more radio stations (fixes Sonos Integration Streaming SiriusXM Shows URL Instead Of Media Info #34128, reverts part of Identify more Sonos radio stations with poor titles #33609)
• Only access variables["enqueued_transport_uri_meta_data"] if it is of the expected type (fixes Webinterface not accessable due to get_states reports error #33952, fixes State is not JSON serializable - Error after update from 107 to 108 #34134, fixes Error After upgrading to version 0.108.3 #34226)
