fix(sidecar): surface visible text on iOS static elements

Static text and button strings live in the accessibility label on
iOS, so the text attribute came through empty and every balance
extractor parsed to zero, silently disarming both folio properties.
Non-editable elements now fall back title, value, then label;
editable fields keep value-only so an empty field's caption does not
read as content.
