Stats: fix month-label placement, back to orange

- labels now sit on the week CONTAINING the 1st of the month (old
  logic labelled the first column starting in that month, so a month
  beginning mid-week was labelled a whole column late — hovering the
  cells under 'Aug' showed Jul dates); skip labels that would crowd
  the previous one
- label + grid rows are inline-flex so flexbox shrink can't drift
  them apart at narrow widths
- cell scale back to the orange accent (color-mix of --acc)
