Connect-time apply pushed persisted zone effects and the LED-control
release write even when the user had LED control switched off — with
the G560 (0x8070) accepting zone writes without a SW-control claim,
Solaar repainted lighting it didn't own on every startup, stomping the
device's onboard effect or any other controller (e.g. OpenRGB).
Off now doubles as "leave the lighting alone": LEDControl.apply skips
the wire entirely unless the persisted value is an explicit claim, and
zone-effect applies follow their control gate (led_control for 0x8070,
rgb_control for 0x8071 — the same gate PerKeyLighting already
enforces). When the gate is on, the claim itself repaints the saved
zone effects, matching the RGBControl claim flow.
