feat(Wizard): Enhance "Write Another" functionality and update accessible descriptions

- Updated the accessible description for the "Write Another" button to clarify its purpose.
- Implemented a new `resetToWriteStep` function to streamline the process of selecting a new storage device while preserving existing settings.
- Introduced a `writeAnotherMode` property to facilitate direct navigation to the writing step after storage selection, improving user experience.
