monitoring(uk-payslip): drop cash PAYE/NI from "Tax & pension — monthly"

Browse source 
Same reasoning as panel 2: cash-side income_tax and NI are inherently
bumpy in vest months due to UK cumulative PAYE catching up on YTD,
and the flat-47% strip can't fix it. Panel now shows only the
explicit RSU vest tax (orange, 47% × rsu_vest), student loan, and
pensions. The smooth view of total cash deductions stays available on
panel 12 (YTD cumulative).
