### Description
This pull request introduces the core functionality for creating and updating posts, completing the backend CRUD operations for the `post` feature. It includes new API endpoints, database schema changes, and corresponding updates across the entire application stack from the database layer to the frontend.
#### Backend API
- **Added new authenticated endpoints:**
- `POST /post`: To create a new post.
- `PUT /post/{id}`: To update an existing post.
- Implemented the full vertical slice for these operations, including:
- `CreatePostUseCase` and `UpdatePostUseCase`.
- Repository and DB service methods for creating, updating, and associating posts with labels.
- Transactional database operations to ensure data integrity when creating/updating posts and their associated labels.
#### Database
- Added a new migration to include an `"order"` column in the `post_label` table.
- This column preserves the user-defined order of labels for each post.
- Queries have been updated to fetch and sort labels based on this new column.
#### API Schema & Documentation
- Enhanced `utoipa` OpenAPI documentation with more specific formats for data types:
- `#[schema(format = Uri)]` for URLs like `preview_image_url`.
- `#[schema(format = Email)]` for user emails.
- `#[schema(format = DateTime)]` for timestamps.
- Standardized the `published_time` field to use the RFC3339 string format instead of a numeric timestamp, improving API clarity and interoperability.
#### Frontend
- Updated the `PostInfoResponseDto` in the frontend to correctly parse the new `DateTime` (ISO string) format for `published_time`.
#### Refactoring
- Renamed `get_full_post` to a more descriptive `get_post_by_id` across the post feature module for better code clarity.
### Package Changes

utoipa = { version = "5.4.0", features = [

### 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
- Change the format of color response
```json
{
"red": 0,
"green": 255,
"blue": 128,
"alpha": 255
}
```
- The relationship between the label's background color and its highlight color is calculated. The method involves first converting the RGB color value to HSL, then decreasing the L (lightness) component, and finally converting it back to RGB.
