Center uneven grid rows.
CSS grid always packs rows from the left, so a last row with fewer cards
than the chosen column count sits flush-left while the rows above are full.
Pure CSS can't center a partial row, so we offset the first card of the last
partial row with grid-column-start.
The grid runs on double sub-columns (each card spans 2 — see
applyAestheticChanges), which is what makes this possible at all: with 3
cards under a 4-card row the leftover space is one column, and centering
needs a HALF-column shift — impossible on plain column lines. On sub-columns
the shift is a whole sub-column (half a card + half a gap), so every
remainder can be centered exactly.
Only runs while Card Grid is on. Skips when the cards overflow the explicit
template (those extra rows are clipped anyway, and the last visible row is
full). Any previously applied offset is cleared first so re-runs (card
hidden/unhidden, dashboard re-render, setting changes) start clean.
