The settings and admin shells reserved the page-heading height in the left
nav with a hidden replica block. The replica wrapped differently in the 220px
nav column than the real heading in the wide content column, so the first nav
item sat too low and drifted across locales.
Hoist the heading into the shell and place it in its own grid row spanning only
the content column: row 1 holds the heading, row 2 holds the nav and the cards.
The nav's first item and the first card now start the same grid row, so they
align by construction regardless of how the title or subtitle wraps. Drop the
spacer component.
