fix(tradein/v2/a11y): немодальный SectionOverlay + контраст токенов + headings — a11y round 3 (#2264)
- SectionOverlay: убран aria-modal (честный non-modal fullscreen-view); focus-trap
  теперь охватывает живой верхний nav + оверлей (query по артборду, фильтр [inert]),
  Tab из nav возвращается в оверлей, не в спрятанный main/footer.
- Контраст 6 muted/disabled токенов затемнён до >=4.6:1 vs worst-case #dce6f1
  (hue сохранён, lightness-only): muted2/3/4, hint, disabledValue/Label.
- accent -> accentDeep как мелкий текст: номер секции оверлея (15px), счётчик
  "Мои отчёты" (10px).
- Семантика заголовков: sr-only h1 «Мера — оценка квартиры» + h2 (оверлей,
  ResultPanel, ObjectSummary, placeholder-панели).
- HeroBar «КОЭФ. ЛОКАЦИИ»: role=button + tabIndex + Enter/Space + aria-label.
- Фокус после успешной оценки переносится на результат-регион (role=region,
  tabIndex=-1, aria-labelledby); live-region «Оценка готова» сохранён.
- Инпут focus-ring усилен (2px solid accentDeep).
- combobox адреса: aria-live анонс количества подсказок; aria-required на
  адрес + площадь; декоративные inline-SVG помечены aria-hidden.
