feat(page-history): «время работы над статьёй» — число в UI + суточный punch-card (#395)

Оценка времени работы над страницей как сессионизация истории page_history по
паузам бездействия (WakaTime-подобно), а не span между крайними правками, плюс
drill-down в суточный таймлайн 24ч×дни. Зависит от #374 (kind + idle-пульс).

Server:
- Чистая computeWorkTime(rows, config) (§5): нормализация+дедуп → коллапс
  агентских всплесков по aiChatId → ОДИН проход сессионизации (порог зависит от
  пары: оба agent → agentTGap, иначе tGap; последняя сессия обязательно
  закрывается) → класс готовой сессии (все agent → agent_only, иначе work) →
  добивка (много-сэмпл → [first−P_in, last+P_out], одиночный скаляр →
  [t−P_single, t]) → метрики = union wall-clock по классу. Детерминированная,
  без БД.
- Чистая bucketByDay(sessions, tz) (§6.3): union work/agent_only РАЗДЕЛЬНО, разрез
  по полуночи tz через нативный Intl (DST-корректно, без «+24ч»). Инвариант
  Σ activeMs == workMs держится по построению.
- PageHistoryRepo.findTimelineByPageId — лёгкая проекция без content, ASC.
- PageHistoryService.computeWorkTime + POST /pages/history/time, гейт
  validateCanView как у /history; атрибуция человек/агент по lastUpdatedSource.

Client:
- usePageWorkTime(pageId) шлёт tz зрителя (Intl локаль).
- Кликабельное число «≈ 4 ч 30 мин» в шапке страницы (порог в тултипе).
- Модалка-punch-card: 24-часовые дорожки по дням, окна work/agent разным цветом,
  одиночные (P_single) приглушены, сумма за день, пустой день «—», сворачивание
  длинных серий пустых дней, подпись tz + T_gap. i18n ru-RU + en-US.

Tests: 22 юнита на computeWorkTime/bucketByDay (§7-фикстура ≈1ч32м vs ≈60h наив,
закрытие последней сессии, коллапс/разрыв всплеска, idle-пульс, DST 23/25ч,
полуночный разрез, инвариант, union-без-задвоения); 5 юнитов гейта контроллера;
int-spec на реальном pg (проекция + совпадение с ядром); 6 клиентских на формат.
