T8b949e/**

* A state holder for managing config data within a Composable.

*

* This class encapsulates the common logic for handling editable state that is derived from an initial value. It tracks

* whether the current value has been modified ("dirty"), and provides simple methods to save the changes or reset to

* the initial state.

*

* @param T The type of the data being managed, typically a Wire message.

* @property initialValue The original, unmodified value of the config data.
