0.3.0

• The sidebar now shows each connected panel's own web interface (the same tab bar, dashboard, settings and logs as its :8888 page) instead of a separate fleet-card list. Pick a panel from the new top menu; add a panel or open the integration's own settings from the same bar. The old placeholder sidebar UI is gone.
• The sidebar's top menu shows the integration's installed version and build number, so checking it no longer needs a diagnostics download.
• Renaming a panel, retrying a failed handover, or losing power partway through no longer leaves a stray or duplicated entity behind.
• Advanced/testing: an optional native transport, set with native_entities: true under panel_assistant in configuration.yaml, lets a panel report state and accept commands over its own authenticated Home Assistant connection instead of MQTT, chosen per panel from the integration's options once turned on. Off by default; MQTT is unaffected either way.
