 * @module KeyValueHeader
 * KeyValueHeader components show breadcrumbs for secret engines.
 *
 * @example
 * ```js
 <KeyValueHeader @path="vault.cluster.secrets.backend.show" @mode={{this.mode}} @root={{@root}}/>
 * ```
 * @param {string} [mode=null] - Used to set the currentPath.
 * @param {string} [baseKey=null] - Used to generate the path backward.
 * @param {string} [path=null] - The fallback path.
 * @param {string} [root=null] - Used to set the secretPath.
 * @param {boolean} [showCurrent=true] - Boolean to show the second part of the breadcrumb, ex: the secret's name.
 * @param {boolean} [linkToPaths=true] - If true link to the path.
