Refactor userId handling in cigarettes and stats routes to use mongoose ObjectId for consistency; add debug logging for stats aggregation.

- Закомментированы секции mongoDb в docker-compose.yml для упрощения конфигурации.
- Добавлена функция getUrl для динамического формирования URL в server.ts, что улучшает обработку запросов в зависимости от окружения.
- Удалены лишние консольные логи из файлов mongo.ts и mongoose.ts для повышения читаемости кода.

+## Правила оформления студенческих бэкендов в `multi-stub`
+
+Этот документ описывает, как подключать новый студенческий бэкенд к общему серверу и как работать с JSON‑заглушками. Правила написаны так, чтобы их мог автоматически выполнять помощник Cursor.
+
+### 1. Общая структура проекта студента
+
+- **Размещение проекта**
+  - Каждый студенческий бэкенд живёт в своей подпапке в `server/routers/<project-name>`.
+  - В корне подпапки должен быть основной файл роутера `index.js` (или `index.ts`), который экспортирует `express.Router()`.
+  - Подключение к общему серверу выполняется в `server/index.ts` через импорт и `app.use(<mountPath>, <router>)`.
+
+- **Использование JSON‑заглушек**
+  - Если проект переносится из фронтенд‑репозитория и должен только отдавать данные, то в подпапке проекта должна быть папка `json/` со всеми нужными `.json` файлами.
+  - HTTP‑обработчики в роутере могут просто читать и возвращать содержимое этих файлов (например, через `require('./json/...')` или `import data from './json/...json'` с включённым `resolveJsonModule` / соответствующей конфигурацией bundler'а).
+
+### 2. Правила для Cursor при указании директории заглушек
+
+Когда пользователь явно указывает директорию с заглушками (например: `server/routers/<project-name>/json`), помощник Cursor должен последовательно выполнить следующие шаги.
+
+- **2.1. Проверка валидности импортов JSON‑файлов**
+  - Найти все `.js` / `.ts` файлы внутри подпапки проекта.
+  - В каждом таком файле найти импорты/require, которые ссылаются на `.json` файлы (относительные пути вроде `'./json/.../file.json'`).
+  - Для каждого такого импорта:
+    - **Проверить, что файл реально существует** по указанному пути относительно файла-импортёра.
+    - **Проверить расширение**: путь должен заканчиваться на `.json` (без опечаток).
+    - **Проверить регистр и точное совпадение имени файла** (важно для кросс‑платформенности, даже если локально используется Windows).
+  - Если найдены ошибки (файл не существует, опечатка в имени, неправильный относительный путь и т.п.):
+    - Сформировать понятный список проблем: в каком файле, какая строка/импорт и что именно не так.
+    - Предложить автоматически исправить пути (если по контексту можно однозначно угадать нужный `*.json` файл).
+
+- **2.2. Проверка подключения основного роутера проекта**
+  - Определить основной файл роутера проекта:
+    - По умолчанию это `server/routers/<project-name>/index.js` (или `index.ts`).
+  - Открыть `server/index.ts` и убедиться, что:
+    - Есть импорт роутера из соответствующей подпапки, например:
+      - `import <SomeUniqueName>Router from './routers/<project-name>'`
+      - или `const <SomeUniqueName>Router = require('./routers/<project-name>')`
+    - Имя переменной роутера **уникально** среди всех импортов роутеров (нет другого импорта с таким же именем).
+    - Есть вызов `app.use('<mount-path>', <SomeUniqueName>Router)`:
+      - `<mount-path>` должен быть осмысленным, совпадать с названием проекта или оговариваться пользователем.
+  - Если импорт или `app.use` отсутствуют:
+    - Сформировать предложение по добавлению корректного импорта и `app.use(...)`.
+    - Убедиться, что используемое имя роутера не конфликтует с уже существующими.
+  - Если обнаружен конфликт имён:
+    - Предложить переименовать новый роутер в уникальное имя и обновить соответствующие места в `server/index.ts`.
+
+### 3. Предложение «оживить» JSON‑заглушки
+
+После того как проверка импортов и подключения роутера завершена, помощник Cursor должен **задать пользователю вопрос**, не хочет ли он превратить заглушки в полноценный бэкенд.
+
+- **3.1. Формулировка предложения**
+  - Спросить у пользователя примерно так:
+    - «Обнаружены JSON‑заглушки в директории `<указанная-папка>`. Хотите, чтобы я попытался автоматически:
+      1) построить модели данных (mongoose‑схемы) на основе структуры JSON;
+      2) создать CRUD‑эндпоинты и/или более сложные маршруты, опираясь на существующие данные;
+      3) заменить прямую отдачу `*.json` файлов на работу через базу данных?»
+
+- **3.2. Поведение при согласии пользователя**
+  - Проанализировать структуру JSON‑файлов:
+    - Определить основные сущности и поля.
+    - Выделить типы полей (строки, числа, даты, массивы, вложенные объекты и т.п.).
+  - На основе анализа предложить:
+    - Набор `mongoose`‑схем (`models`) с аккуратной сериализацией (виртуальное поле `id`, скрытие `_id` и `__v`).
+    - Набор маршрутов `express` для работы с этими моделями (минимум: чтение списков и элементов; по возможности — создание/обновление/удаление).
+  - Перед внесением изменений:
+    - Показать пользователю краткий план того, какие файлы будут созданы/изменены.
+    - Выполнить изменения только после явного подтверждения пользователя.
+
+### 4. Минимальные требования к новому студенческому бэкенду
+
+- **Обязательные элементы**
+  - Подпапка в `server/routers/<project-name>`.
+  - Основной роутер `index.js` / `index.ts`, экспортирующий `express.Router()`.
+  - Подключение к общему серверу в `server/index.ts` (импорт + `app.use()` с уникальным именем роутера).
+
+- **Если используются JSON‑заглушки**
+  - Папка `json/` внутри проекта.
+  - Все пути в импортирующих файлах должны указывать на реально существующие `*.json` файлы.
+  - Не должно быть «магических» абсолютных путей; только относительные пути от файла до нужного JSON.
+
+- **Если проект «оживлён»**
+  - Папка `model/` с моделью(ями) данных (например, через `mongoose`).
+  - Роуты, которые вместо прямой отдачи файлов работают с моделями и, при необходимости, с внешними сервисами.
+
+Следуя этим правилам, можно подключать новые студенческие проекты в единый бэкенд, минимизировать типичные ошибки с путями к JSON и упростить автоматическое развитие заглушек до полноценного API.

Чтобы избежать этого, важно тщательно проработать каждый раздел документации и убедиться, что все примеры корректны и понятны.\n\n## Контекстуализация\n\nТекст для анализа:\n\n**Description**: This is a simple Python script that calculates the average value of a list of numbers.\n\n**Code Block**: \n```python\ndef calculate_average(numbers):\n    \"\"\"Calculate the average value of a list of numbers\"\"\"\n    return sum(numbers)/len(numbers)\n```\n\nПримеры использования:\n\n```python\n# Example usage\nnumbers = [10, 20, 30]\naverage = calculate_average(numbers)\nprint(\"The average value of the list\", numbers, \"is\", average)\n```\n\n## Упражнения\n\nПисьменное задание: Написать документацию для простой функции на языке Python, которая принимает список чисел и возвращает среднее значение. Включить описание, код блока и пример использования.\n\nУстная практика: Ролевой диалог между разработчиком и техническим писателем о структуре и содержании документации программы.\n\nАналитическое задание: Проанализировать существующую документацию программы и найти ошибки или неясности. Предложить улучшения.\n\n## Домашнее задание\n\nТекстовые задачи:\n\n- Написать документацию для другой функции на языке Python, используя правильную структуру.\n- Исправить ошибки в существующей документации программы.\n- Перевести фрагмент документации на русский язык, сохраняя точность и стиль.\n",

These verbs are able to express multiple meanings depending on their use in a sentence.\n\n## Learning Objectives\n\nBy the end of this unit, you will be able to:\n\n* Identify the different forms of the main multifunctional verb.\n* Explain how these forms can be used interchangeably in sentences.\n* Demonstrate the correct usage of the three forms of the multifunctional verb by providing sentences and examples.\n\n## Vocabulary Review\n\n| Term | Definition                                               |\n| ---- | -------------------------------------------------------- |\n| Be   | To express a present or ongoing state of being.          |\n| Have | To express ownership or possession.                      |\n| Do   | To express an action to be done, future action or habit. |\n\n## Activities\n\n### Activity 1: Identify the Different Forms of the Main Multifunctional Verb\n\n* Read through each sentence and identify if the verb is used in its present tense (is), past tense (was/were), or future tense (will, would).\n* Discuss how this usage can vary depending on context.\n* Write down sentences that use different forms to illustrate your points.\n\n1. **Sentence 1**\n\n   : \"The cat is sleeping.\"\n   * Present tense: The cat is sleeping.\n   * Past tense: The cat slept.\n   * Future tense: The cat will sleep.\n2. **Sentence 2**\n\n   : \"I have a dog at home.\"\n   * Present tense: I have a dog.\n   * Past tense: I had a dog.\n   * Future tense: I will have a dog.\n3. **Sentence 3**\n\n   : \"We are going on a hike tomorrow.\"\n   * Present tense: We are going on a hike.\n   * Past tense: We went on a hike.\n   * Future tense: We will go on a hike.\n4. **Sentence 4**\n\n   : \"He has been studying all day.\"\n   * Present tense: He is studying.\n   * Past tense: He studied.\n   * Future tense: He will study.\n5. **Sentence 5**\n\n   : \"We are going to buy some groceries later today.\"\n   * Present tense: We are going to buy some groceries.\n   * Past tense: We bought some groceries.\n   * Future tense: We will buy some groceries.\n\n### Activity 2: Explain How These Forms Can Be Used Interchangeably in Sentences\n\n* Read through a sentence and identify the present, past, and future tense uses.\n* In pairs, explain why these forms are used interchangeably.\n* Provide examples of sentences that demonstrate this usage.\n* Highlight how the context changes the meaning.\n\n### Activity 3: Correct Usage of the Three Forms of the Multifunctional Verb\n\n* Read through a sentence and identify which form is being used.\n* In pairs, discuss why these forms are used in certain situations.\n* Provide sentences that demonstrate the correct usage of the three forms.",
