refactor: период через period.from вместо last_used; дедуп удалён

Удалены last_used, precision, dynamic и дедупликация по created_on/updated_on. Период задаётся одним полем period.from (env FROM_DATE), окно -- от этой даты до сегодня. После успешного --commit/--send начало окна сдвигается на конец отчёта; datetime-границы --date приводятся к полным дням. Схема конфига ломающая: старые ключи игнорируются, миграция описана в документации.
