cync_lan (Home Assistant custom_component) v2.5.0

Writes to a sleeping motion sensor are now refused instead of vanishing.

Battery devices - motion sensors, and the wireless switches and remotes that
share their behaviour - only join the mesh while awake. A settings or schedule
write aimed at a sleeping one never reaches it. Previously the two
experimental_set_motion_sensor_* actions and the "Experimental commands"
schedule form sent regardless, so the command disappeared and nothing said why.

All of them now check the device is awake first and refuse with an error asking
you to hold its off button for five seconds until the LED turns green. The
guided "Edit motion sensor settings" wizard already did this; the other three
paths did not, and now share the same check.

The check is the device's ordinary online status, which is what the real Cync
app uses too - its wake-up screen watches the same availability signal every
device type reports, and no separate "discoverable" state exists to detect.
Where this deliberately differs from the app: the app sends anyway and reports
success without transmitting. A silent no-op there is indistinguishable from a
wrong opcode, and would send you debugging the protocol instead of pressing a
button.
