VAT breakdown: rate/amount right-aligned under the Gesamtsumme € amount

Same row shape as the Gesamtsumme total line itself (label left, flex-1
spacer, value right) instead of the grid — label stays flush with
"Gesamtsumme", rate+amount land flush right under the total's own €
figure. Fixed-width rate column keeps multiple rates aligned to each
other regardless of digit count.

-// Multi-rate case is a 3-column CSS grid (label / rate / amount), not a
-// flex column — the "enthält MwSt.:" label only occupies row 1's first
-// cell (later rows get an empty cell there), so the first rate sits on
-// the *same line* as the label instead of dropping to its own row below
-// it. Grid (unlike stacked flex rows) sizes each column to the widest
-// cell across every row automatically, so the rate column still lines up
-// a single-digit rate ("7%") under a two-digit one ("19%") without
-// needing an explicit fixed width.
+// Same row shape as the Gesamtsumme total line right above this
+// (`flex w-full` + a `flex-1` spacer): a label on the left, flush with
+// "Gesamtsumme", and the rate/amount pushed flush right so they land
+// directly under the total's own € amount — not tucked in right next to
+// the label. The rate itself gets a fixed-width right-aligned column
+// (`w-8`, `tabular-nums`) so a single-digit rate ("7%") still lines up
+// under a two-digit one ("19%") across rows instead of shifting the
+// amount that follows it. Only the first row carries the "enthält
+// MwSt.:" label; further rates repeat just the rate/amount pair.
