fix(aegis): 0.9.9 — address columns share one grid so they line up

Each .warow was its own grid container, so the `auto` amount column
resolved independently per row: a row holding 0.3066756 got a narrower
column than one holding 0.43789841, and the copy button therefore landed
at a different x on every line. Column widths have to be SHARED to line
up, and nothing was sharing them.

The columns are now declared once on a .walist wrapper and every row
inherits them via `grid-template-columns: subgrid`. Column gaps moved to
the parent, since a subgrid takes its gutters in the subgridded axis from
the grid it inherits and would have ignored them on the row. A
@supports fallback pins the amount column to a fixed 104px for any host
without subgrid, which keeps the copy column straight there too.

Measured across six rows with four different amount lengths, at 260,
320, 400 and 520px wide: copy left edge, amount right edge, ticker left
edge and menu right edge all have 0px spread, with no row overflow and
no clipped amount.

0.9.8 claimed this area was verified, but the check only looked for cell
overlap WITHIN each row and never compared the same column ACROSS rows —
which is exactly the defect it missed.
