Fix AI Companion recordings list top alignment in scroll view

Wrap the list stack in a document container with the same Auto Layout
pattern as Settings: pin document top/leading/trailing/width to the clip
and use bottom >= clip.bottom plus bottom >= stack.bottom so short
content no longer stretches the stack and pins rows to the bottom.
