upg-100 legend: drop the People Group tab, which could never render anything

The Driver said "it doesn't need to have a People Group tab inside the legend".
The reason is stronger than preference: clicking it showed nothing at all.

SemanticTreeLegend renders tab N as collectAtDepth(nodes, N) -- a tab's INDEX
IS a tree depth. This legend's tree is exactly TWO levels: 9 regions -> 28
lists. MEASURED by expanding every caret on the Region tab: 37 rows, 9 at
indent 0 and 28 at indent 1, deepest level 1. There is no level 2, so tab index
2 resolved to an empty set and the panel rendered its "No data at this level"
empty state with the tab ACTIVE and selected.

★ THIS IS WHY PART (c) WAS GATED AND NO LONGER IS. The card asks "what is the
legend's intended tree once Region/Zone/People Group are removed" -- a real
question, still the Driver's. But removing a tab that is STRUCTURALLY INCAPABLE
of content needs no ruling about intent. It is a defect, not a design choice.

AFTER: two tabs, both with content -- Region 9 rows (expandable to the 28) and
UPG-100 Lists 28 rows. Clicking every remaining tab and info button, 6 elements
in total, produces ZERO empty states.

⚠ THE i18n KEYS ARE DELIBERATELY LEFT IN PLACE. 22 locale files carry
upg100Group; deleting them costs 11 languages of re-translation if a third
level ever arrives, while an unused key costs nothing at runtime and the parity
gates assert presence rather than usage. Removing them would be the riskier
edit, not the tidier one.

⚠ AND A THIRD TAB IS NOT THE MECHANISM if people-group rows are ever wanted.
The tree would need a third level (list -> group); re-adding the tab without
deepening the data reproduces exactly this empty state.

check:a11y-button-names PASS, and check:legend-info-localized PASS on this leaf

0 blank.
