ESPHome stops servo blinds moving when their control signal ends

ESPHome corrects a brief, unwanted servo movement when an ESP32 stops driving its control signal. Setting the output to zero previously cut the final pulse short; the correction lets that pulse finish before applying zero at the next cycle.

Tomas Matheson reproduced blinds sporadically reopening after automatic detachment and reports that the correction stops it on his setup. This is his first contribution to ESPHome.
