A TextPreviewController (owned by the viewer, bound by MediaTextPreview) mirrors the editing/dirty/saving state out so the top bar draws the buttons; Save shows a spinner while saving. Located and tested via a Codex consult (its end-to-end widget test, with the provider fixed and the saving state adapted); the controller design replaces its builder-wrapping patch.
