uk-payslip dashboard: count gross comp on taxable_pay (P60) basis
The 'Yearly receipt' + 'YTD gross salary' panels summed salary+bonus+rsu_vest
(rsu_vest = net/partial RSU), understating gross by ~£73k/yr. Switch to
COALESCE(taxable_pay, gross_pay) + pension_sacrifice = true P60 gross (verified:
23/24 -> £286,288, 25/26 -> £416,646, matching the P60 + job-hunter realized
bar). 'Yearly receipt' rsu_gross is now the real gross RSU (£150k/£271k, not
£70k/£128k). Relabel the Sankey RSU inflow 'RSU (net vested)' for honesty;
leave cash-flow/net_pay + the (taxable_pay-based) reconciliation/rate panels.
