The month grid was inset 4dp while its weekday header (and the loading grid) used
8dp, so the week-number column — and the day cells under their labels — sat 4dp
left of where they should. Bring the grid to 8dp: the gutter centre now lands on
the hamburger (4dp bar inset + 24dp half icon), and day cells sit under their
weekday labels.
The week view's header badge and hour labels had the same drift (a 48dp edge-to-
edge gutter centres its content at 24dp, not 28dp). Its top section background
bleeds full-width when scrolled, so instead of insetting the whole content, give
just the gutter content an 8dp start inset to centre it on the hamburger too.
