feat: OnlyOffice Standalone integration with S3 direct URLs

✅ ЧТО СДЕЛАНО:
- Поднят новый standalone OnlyOffice Document Server (порт 8083)
- Настроен Nginx для доступа через office.clientright.ru:9443
- Создан open_file_v3_standalone.php для работы с новым OnlyOffice
- Реализована поддержка прямых S3 URL (bucket публичный)
- Добавлен s3_proxy.php с поддержкой Range requests
- Создан onlyoffice_callback.php для сохранения (базовая версия)
- Файлы успешно открываются и загружаются!

⚠️ TODO (на завтра):
- Доработать onlyoffice_callback.php для сохранения обратно в ОРИГИНАЛЬНЫЙ путь в S3
- Добавить Redis маппинг documentKey → S3 path
- Обновить CRM JS для использования open_file_v3_standalone.php
- Протестировать сохранение файлов
- Удалить тестовые файлы

📊 РЕЗУЛЬТАТ:
- OnlyOffice Standalone РАБОТАЕТ! ✅
- Файлы открываются напрямую из S3 ✅
- Редактор загружается БЫСТРО ✅
- Автосохранение настроено ✅ (но нужна доработка callback)
