Feat/avatar upload

[benedictfred]

Description

This pull request introduces a user avatar upload feature to the backend, enabling users to upload, process, and store profile images using AWS S3. The implementation includes image validation and optimization, integration with AWS S3 for storage, and updates to the user entity and API endpoints to support avatar management.

Changes Made

Avatar Upload and Processing

• Added a new endpoint PATCH /users/me/avatar in UsersController to handle user profile image uploads, including validation for image type and processing with a custom SharpPipe for resizing and converting images to optimized WebP format.

AWS S3 Integration

• Created UploadService for uploading processed images to AWS S3 using the AWS SDK, with configuration loaded from environment variables.
• Added new dependencies for AWS SDK, multer, and sharp for image processing and S3 integration.

User Entity and Service Updates

• Updated the User entity to include an optional avatar_url field for storing the image URL.
• Implemented updateUserProfilePicture in UsersService to handle image upload, storage, and updating the user's avatar URL in the database.

Module and Dependency Wiring

• Registered UploadModule and UploadService in relevant modules to ensure dependency injection and service availability for user-related operations.

These changes collectively provide a secure, efficient, and scalable solution for user avatar uploads and management.
