Shutter: fix ShutterButton MQTT flag parameters on ESP32 (#25116)

The MQTT flags m1, m2, m3 and mh were stored one slot too high
(position[i-6]), so mh set the triple press flag and m1 wrote before
the start of the position array. mi (mqtt_all) could not be set at all.

Store m1..mh in position[0..3], set mqtt_all from mi and include it in
the command response, as the ESP8266 driver already does.

Fixes #25082
