pcp: время — сквозной naive LocalDateTime как локальное настенное время (без UTC)

Отказ от остаточной UTC-семантики: naive LocalDateTime трактуется как
локальное время единой зоны всех сервисов.

Backend (границы внешних систем):
- VisibilityPayloadParser, SyncSpacecraftFromNsiUseCase: ZoneOffset.UTC →
  ZoneId.systemDefault() для проекции внешних Instant/ISO-с-Z в naive.
- тесты границ перевёрнуты на systemDefault (под Europe/Moscow ждут +3).
- чистка UTC-формулировок в DTO-комментариях, мёртвых ссылок на
  docs/standards/DATETIME_UTC.md.

Frontend (pcp-tgu-ops-ui):
- utils/utcTime.ts → utils/localTime.ts: parseLocal/formatLocal*/toLocalIso/
  toLocalInputValue с локальной семантикой (без дописывания Z и timeZone:UTC).
- замена getUTC*/Date.UTC/toISOString-сериализации на локальные аналоги.
- убраны пользовательские подписи «UTC» в редакторе/таймлайне.
- удалён utcTime.guard.test.ts (форсил обратный UTC-инвариант); тест-фикстуры
  сделаны зоно-независимыми. tsc + vitest зелёные под TZ=UTC и TZ=Europe/Moscow.

Включает также прочие незакоммиченные правки рабочего дерева.
