monitoring(uk-payslip): promote yearly receipt + YTD gross YoY to row 4

Move both barchart/timeseries panels into row 4 (y=29, side-by-side
w=12 each, h=10) so the per-tax-year overviews appear right after
the income-tax-and-pension YTD row. Shift panels 13, 4, 5, 6, 8, 9
down by 10 to accommodate.

Final ordering: rows 1–3 = monthly + YTD timeseries (panels 1/7/2/3/11/12),
row 4 = yearly receipt + YTD gross YoY (16/17), then the wider
deduction/integrity/table panels below.
