Add device type 105 (SingleChipFullColorBulbA21Gen2 / "Direct Connect A21") to Capabilities table

[imwithsam]

Device type 105 (GE Cync "Direct Connect A21" full-color bulb — confirmed via live account data) is missing from every capability list in Capabilities (ONOFF, BRIGHTNESS, COLORTEMP, RGB, WIFICONTROL). Since every derived capability flag is device_type in Capabilities[...], this causes the integration to treat these bulbs as having zero capabilities at all — no entity created correctly, missing from switchID_to_homeID/home_controllers since WIFICONTROL gates that. Confirmed the correct classification independently against the official cync integration's own device table (pycync), which already maps 105 → SingleChipFullColorBulbA21Gen2.

Diff (in cync_hub.py, top of file):

Tested live: confirmed the fix produces a correctly-derived config (all capability flags True, proper switch_controller/switchID_to_homeID entries) via a fresh account login, entities register cleanly with no errors.
