fix(quickshell): drop layout-overridden geometry in HostPanel

The expanded body is a RowLayout, so the divider's `y`/`width`/`height`, the
clock column's `width: 210`, and the user/zone text's `y: 32` were all being
discarded silently — a layout assigns its children's geometry, and a Column
positions its own. Only the anchors among these ever warned.

The divider's 8px inset becomes Layout margins, and `Layout.alignment` goes
from the clock column, where it is ignored while the item fills.
