/**
 * A custom validator function that applies conditional validation logic
 * based on a user-defined configuration.
 *
 * The function evaluates a `condition` provided in the configuration to determine
 * whether the associated `validator` function should be applied to the control.
 * It also tracks changes to relevant fields in the form and revalidates the control
 * whenever any of the dependent fields are updated.
 *
 * This supports dynamic validation scenarios where the validity of a control
 * is determined by its relationship with other controls in the form.
 *

 *                                              the condition function and the validator.
 * @returns {ValidatorFn} A validator function that implements the conditional validation logic.
