### Description
This PR introduces full CRUD (Create, Read, Update) functionality for post labels, implemented by following the existing Clean Architecture.
#### Backend
* **New API Endpoints for Label Management:**
* `POST /label`: Create a new label (**authentication required**).
* `PUT /label/{id}`: Update a label by its ID (**authentication required**).
* `GET /label`: Get all labels.
* **Architectural Implementation:**
* **Delivery Layer**: Added `CreateLabelRequestDto`, `UpdateLabelRequestDto`, and updated `PostController` with methods to handle label-related operations.
* **Application Layer**: Created corresponding use cases (`CreateLabelUseCase`, `UpdateLabelUseCase`, `GetAllLabelsUseCase`) to handle business logic.
* **Gateway/Framework Layer**: Implemented `LabelRepository` and `LabelDbService` to manage database interactions, including creating, updating, and querying labels.
* **Route Adjustment:**
* The route for fetching all post info has been changed from `GET /post/all` to `GET /post` to be more RESTful.
#### Frontend
* **API Call Update:**
* To match the backend route change, the API path for fetching all posts is updated from `/post/all` to `/post`.

### Description
This PR integrates the **`utoipa`** and **`utoipa-redoc`** crates to automatically generate OpenAPI-compliant API documentation for the backend project.
#### Overview
To improve development efficiency and API maintainability, this change introduces `utoipa` to automate the API documentation process. By adding specific attribute macros to the source code, we can generate detailed API specifications directly and serve them through an interactive UI provided by `utoipa-redoc`.
#### Key Changes
* **Dependencies Added**
* Added `utoipa`, `utoipa-gen`, and `utoipa-redoc` to `Cargo.toml`.
* `utoipa` is used to define OpenAPI objects.
* `utoipa-redoc` is used to serve the ReDoc documentation UI.
* **Code Refactoring**
* **HTTP handler logic** in each feature (`auth`, `image`, `post`) has been extracted from the `..._web_routes.rs` files into their own dedicated files (e.g., `get_post_by_id_handler.rs`). This makes the code structure cleaner and simplifies adding documentation attributes to each handler.
* Renamed the `PostController` method from `get_full_post` to `get_post_by_id` for a more RESTful-compliant naming convention.
* **API Doc Annotation**
* Added `#[derive(ToSchema)]` or `#[derive(IntoParams)]` to all DTOs (Data Transfer Objects) so they can be recognized by `utoipa` to generate the corresponding schemas.
* Added the `#[utoipa::path]` macro to all HTTP handler functions, describing the API's path, HTTP method, tags, summary, expected responses, and security settings.
* **Doc Aggregation & Serving**
* Added an `..._api_doc.rs` file in each feature module to aggregate all API paths within that module.
* Added a new `api_doc.rs` file in the `server` crate to merge the OpenAPI documents from all features, set global information (like title, version, and the OAuth2 security scheme), and serve the documentation page on the `/redoc` route using `Redoc::with_url`.
### Package Changes
```toml
utoipa = { version = "5.4.0", features = ["actix_extras"] }
utoipa-redoc = { version = "6.0.0", features = ["actix-web"] }
