fix(theme): readable text on any operator palette + admin consistency pass

Контраст-аудит (WCAG-обход всех текстовых узлов, 4 палитры × юзер+админ
страницы) показал системные провалы читаемости: вторичный текст 1.5-2.5
на светлой/кастомных темах, статусные цвета 1.3-1.6, белый текст на
светлых акцентах 1.9.

Корневые фиксы:
- useThemeColors: контраст-кламп производных серых токенов — dark-400/
  champagne-600 (вторичный текст) держат >=5.0 к поверхности, dark-500/
  champagne-500 (подсказки) >=3.8; палитры с достаточным контрастом
  рендерятся байт-в-байт как раньше
- --color-on-accent/-success/-warning/-error: чёрный или белый текст
  по фактической яркости цвета оператора; text-white на accent-заливках
  заменён на text-on-accent (135 мест + variant примитива Button +
  .btn-primary)
- .light: статусные текстовые оттенки *-300/400 ремапятся на тёмные
  *-700 (жёлтая «Админка» 1.26 -> 3.8+, зелёные суммы 1.4 -> 3.4+,
  бейджи состояний)

Замер после: операторская тёмная палитра — 0 нарушений (всё >=4.5),
худшие точки остальных подняты с 1.26-1.6 до 3.2+.

Консистентность:
- заголовки админ-страниц приведены к text-xl font-bold text-dark-100
  (были 18/20/24/30px и 600/700 вперемешку)
- «Создать FAQ»: warning-500/80+белый -> warning-500+text-on-warning
- formatTraffic: единицы из i18n (убран микс «GB»/«ГБ» на одном экране)
- categoryCanvas -> categoryCANVAS в локалях (битый ключ на настройках)
- «Управление сквадами» -> «Управление локациями» (юзерский экран)
- мин-макс сумм на выборе метода: dark-600 -> dark-400
- неактивные пункты нижнего нава: dark-500 -> dark-400
