Autorestore fixes:
- Snapshot WLED state before connect() mutates it (lor, AudioReactive)
- Gate restore on auto_shutdown setting (was unconditional)
- Remove misleading auto_restore capability from serial provider
- Default auto_shutdown to false for all new devices
Protocol badge fixes:
- Show correct protocol per device type (OpenRGB SDK, MQTT, WebSocket)
- Was showing "Serial" for all non-WLED devices
