Move background + conclusions below the issues on compose

The right sidebar with "רקע לניתוח" and "מסקנות" was stealing
horizontal space and forced the editable cards (threshold claims,
issues, chair positions, now precedents) into a narrow column. Move
both cards into the main stack, after the issues list, so the chair
sees the decision points first and the surrounding context after.

Collapse the lg:grid-cols-[1fr_320px] layout into a single max-w-4xl
stack since there's no longer a sidebar. Bump the moved cards from
px-5 py-4 to px-6 py-5 to match the rest of the compose page's
card padding.
