v1.6.0b0

What's Changed

Allow the universal media player to be fully configured and managed from the Home Assistant UI, without writing YAML by hand.

• Add a guided setup wizard that picks the device class and suggests relevant commands and children entities automatically.
• Let users assign, per command category, which child entity and service handles each action.
• Support reconfiguring an existing entry from the UI instead of editing configuration.yaml
• Support importing existing YAML-based media player configs into a config entry
