feat: add ON/OFF action config for Countdown and Away rules in Homebridge plugin

- Countdown: new 'Action when timer fires' dropdown (Turn ON / Turn OFF);
  scheduler uses rule.countdownAction instead of hardcoded 1/0
- Away Mode: scheduler now reads startAction/endAction from the rule
  (UI already exposed these fields); _stopAwayLoop respects endAction
  instead of always forcing OFF at window end
