fix(number-fields): избегаем потери точности длинных чисел

- number-поля теперь рендерятся как text + inputMode=numeric,
  чтобы браузер не округлял значения через input type=number
- пробелы при вставке в number-поля удаляются
- бэкенд нормализует значения number-полей в строку перед сохранением
- добавлен хелпер normalizeFieldValueForStorage

Closes: искажение расчётного счёта и других длинных числовых полей
