pcp: единообразие времени (UTC) по группе сервисов

Фронт (pcp-tgu-ops-ui):
- тест-страж utcTime.guard.test.ts: запрещает Date.parse / new Date(string) /
  toLocale* без timeZone вне utils/utcTime; тестовые фикстуры переведены на parseUtc.

Бэкенд:
- UTC-now: LocalDateTime.now() -> LocalDateTime.now(ZoneOffset.UTC) по всем сервисам
  (entity-дефолты, воркеры, use case'ы) и в тестовых фикстурах.
- Конвертации к UTC (баги на не-UTC JVM, каждая с регресс-тестом в не-UTC поясе):
  - tgu: VisibilityPayloadParser, SyncSpacecraftFromNsiUseCase (Instant -> UTC LocalDateTime);
  - mission-planing: MissionPlaningService (OffsetDateTime -> UTC через toUtcLocalDateTime);
  - dynamic-plan: RequestServiceClient (OffsetDateTime -> UTC);
  - slots: SlotRepositoryImpl (getObject(LocalDateTime) вместо getTimestamp().toLocalDateTime()).
- Контрактные сериализационные тесты формата на проводе (naive без зоны / Z):
  PlanResponse (tgu), RequestResponseDto (request, эталон), TguPlanning DTO (ui).
- KDoc-инвариант «=UTC» на UI-facing DTO (tgu PlanResponse, ui-service DTO вкладки ТГУ).

Документация: docs/standards/DATETIME_UTC.md (соглашение, таблица сервисов, под-задачи на миграцию к Z),
docs/standards/CHECKLIST.md (пункт про UTC на API).
