feat(market): fix portfolio Add button clipping; add accordion summaries

- Add button can no longer be cut off: it's now a normal widget below the group
  list (in a group with the scroll child) instead of nested inside the list child.
- Stop the modal's 28x20 WindowPadding from cascading into the nested master/detail/
  list children (pop it right after the card child begins) — that double-padding
  was squeezing the master column and the Add button.
- Right pane navigability: collapsed accordion sections now show a compact summary
  on the right (Appearance -> icon, Price -> basis, Addresses -> N selected), so a
  group's state is readable without expanding. Section titles are consistent
  title-case ("Appearance"/"Price"/"Addresses").
