feat(app): редизайн Обзора под новый визуальный язык

Локальные _StatTile/_ChartCard заменены на общие StatTile/SectionCard,
блоки капитала/месяца/инвестиций получили SectionHeader, ряды плиток
переведены с Wrap на TileCarousel. Заодно цвет «ок» в чипе качества
данных переведён с хардкод Colors.green на ChartColors.slot3Aqua —
тот же цвет, что signColor уже использует для положительного знака.
