feat: restructure generator modal into two-zone layout

Split the single-column generator modal into a Selection zone (what to
include) and Configuration zone (how to output) using CSS grid, with a
full-width footer for action buttons. Adds note count indicator and
token estimate from existing context files. Responsive: side-by-side
on wide viewports, stacked on narrow.
