ha: add carefree_bt12 integration for the Carefree Connects awning

Commands reverse-engineered from Bluetooth HCI snoop captures (adb bugreport) of the official Carefree Connects (BT12) Android app, confirmed across three independent captures including two isolated single-action live tests: extend/retract (feature 0x05, values 0x01/0x02 -- the device toggles motor state internally, there's no separate stop byte) and light on/off (feature 0x1a, values 0x19/0x01). Both live under GATT characteristic 02060002 on service 02060001-50e1-405f-bab0-6bb582b4d96e. Connects on demand per command (mirrors the app's own connect/act/disconnect pattern) rather than holding a persistent connection like li3_battery, since this device doesn't stream telemetry. Cover/light state is assumed/optimistic -- the notify channel (02060003) isn't decoded yet, so a diagnostic sensor just surfaces raw undecoded replies to build up data for that follow-on work. Verified end-to-end against the real device: light on/off and awning extend both worked through Home Assistant. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
