User profile picture upload

[andrewquach-dev]

Description: Allow users to upload profile pictures to personalize their user profiles. Implement the necessary backend logic and user interface components to handle profile picture uploads. Validate uploaded images and provide feedback to users in case of any errors or invalid formats. We're going to use Cloudinary API for photo uploads since everyone is familiar with it unless someone has other suggestions.

Checklist:

• [ ] Read Cloudinary API documentation
• [ ] Follow along Leon's implementation (https://github.com/resilientcoders/quick-pound-bootcamp/blob/main/middleware/cloudinary.js)
