fix: закрыть IDOR в бронях, пароль админа и обработку callback_data (PRJ-3)

- IDOR: отмена/редактирование брони только владельцем (проверка user_id)
- пароль админа: убран дефолт admin123, обязателен из env; сравнение через hmac.compare_digest; TTL сессии 1ч
- callback_data: безопасный парсинг int + .get() вместо прямого индексирования (KeyError/ValueError)
