feat: режим индикаторов без цветовой кодировки + переустройство /setup

Новая настройка app_settings.indicator_mode (color | accessible), переключается
на /setup. В режиме accessible сигналы, которые раньше держались только на цвете,
переходят на форму/текст:
- качество цены (0-9) — 5-ступенчатый signal-meter вместо градиентной точки/числа;
  единый модуль web/static/price-quality.js, ветвление по window.QF_INDICATOR_MODE;
- вкладка «Ценообразование»: ведущая колонка-meter вместо заливки строк,
  пометка W вместо амбер-подсветки world-цен, ⚠ вместо красного «загрязнённого» итога.
- GET/PUT /api/settings/ui (без рестарта), регистрируется в обоих наборах роутов.

/setup переустроен: две колонки одной высоты, кнопка «Вернуться в приложение»,
исправлен <title>.
