📝 Логирование + graceful shutdown

- Добавлен app/logger.py — loguru с ротацией (консоль, файл, ошибки)
- main.py: логи старта/стопа, graceful shutdown (SIGTERM/SIGINT/stop_signal)
- Все хендлеры: логирование ключевых действий пользователя
- Логи сохраняются в logs/bot_YYYY-MM-DD.log, ротация 30 дней
- Ошибки отдельно в logs/errors_*
