Replaces the old narrow four-card All-Time/YTD row (dropped in Task 9)
with two wider cards under a numbered 'Chapter I - Lifetime Context'
heading. Projects card gains Start, Working Days, Total Cost, and
Avg R / Working Day columns per the design. Teams card keeps name +
total.
Adds .chapter-heading and .chapter-num CSS for the orange numbered
markers (I, II, III, IV) and .report-numeric class that applies
tabular-nums across the number columns of every report table.
Renames the existing 'Selected Period' heading to Chapter II.
