P2 Badge Reuse the existing wide-block result

For every assistant-message render, this repeats the identical hasWideMarkdownBlock call already made in hasWideBlock above. On Android, ordinary long messages without an early match make the helper split and scan the entire message twice; while an assistant response is streaming, that redundant linear work and allocation recurs on every update in the performance-sensitive feed. Use the existing hasWideBlock value for the assistant width condition instead.
