Fix incorrect handling of openState in Contact Sensor (#1061)

## ♻️ Current situation

The Contact Sensor has three states: `open`, `close`, and
`timeOutNotClose`[^1]. `timeOutNotClose` indicating that the door/window
has been open for an extended period. However, in the current
implementation, the `timeOutNotClose` state is not handled correctly,
causing the state to be incorrectly updated to `close`.

## 💡 Proposed solution

I modified the handling so that `timeOutNotClose` behaves the same as
`open` state, and I created a private function for shared handling to
prevent future bugs.

## ⚙️ Release Notes

- Fix incorrect handling of openState in Contact Sensor
