Four frontend display fixes for the Site Finder analysis report (audit #1953);
all consume fields the (already-deployed) backend now returns.
- #1954: ЕГРН «Обременения» row was hardcoded «—». Wire top-level
`encumbrance` block {has_zouit, zouit_count, zouit_types} via
formatEncumbrance → «ЗОУИТ: N (types)» / «не выявлено (НСПД)».
- #1955: show obj_class per success bucket («Студии 15-30 · Комфорт») so
rows with identical area-labels are distinct; fix top-row match + React key
to (bucket, obj_class).
- #1957: NspdZouitOverlapsBlock renders human type_zone + reg_numb_border,
adds a СЗЗ caveat banner (СанПиН 2.2.1/2.1.1.1200-03) and «СЗЗ вашего
участка» highlight; switched raw hex to UI tokens.
- #1958: ForecastChart axis names → nameLocation:middle + nameGap (no legend
overlap); grey flat-state callout when the deficit line is degenerate
(scenarios_collapsed or all points clamped at ±1).
Tests: formatEncumbrance + isDeficitDegenerate (15 new). Real segment
differentiation is backend #1959 (separate).
