Show an extract-text button (document icon) in the bottom bar when the current image has no extracted text yet. Clicking it calls the extract-text API, shows a spinner while in progress, and on success replaces itself with the text-lines display button and auto-opens the overlay. Error state briefly turns the button red. Resets on every item navigation alongside the other text state. Hidden for videos and items without an itemKey.
