Each expandable row now has a text input + Ask button alongside the
auto-analysis. Type any question about that row, press Ask or Enter, and
the answer streams in below via the existing /explain SSE path.
Server: row mode accepts an optional "question" field — when set it uses
a grounded Q&A prompt instead of the default analysis. Adds askRow() JS
handler, row-ask markup, and supporting CSS.
