[FEAT] Integrate Unsplash and Upload (minio) for images

[martian56]

This pull request introduces several new features and enhancements related to user profile, project, and workspace image handling, as well as new API endpoints for file uploads, Unsplash image search, and user favorite projects. It also integrates MinIO for file storage and updates relevant data models and handlers to support these capabilities.

File Uploads and Image Handling

• Added a new UploadHandler with endpoints to upload images to MinIO and serve files, supporting avatars, cover images, and logos. The MinIO client is now initialized optionally and injected into the router and handlers. (api/internal/handler/upload.go, api/cmd/api/main.go, api/internal/minio/minio.go, api/internal/router/router.go) [1] [2] [3] [4] [5]
• Extended user (User), project (Project), and workspace models and update handlers to support avatar, cover_image, and logo fields, allowing users and projects to have associated images. (api/internal/model/user.go, api/internal/model/project.go, api/internal/handler/auth.go, api/internal/handler/project.go, api/internal/handler/workspace.go) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

API and Integration Enhancements

• Added a new handler and endpoint to proxy Unsplash image search, allowing the frontend to search for Unsplash images using a configured API key. (api/internal/handler/instance.go)

User Favorites Feature

• Introduced a new FavoriteHandler and supporting store/service to allow users to list, add, and remove favorite projects via API endpoints. (api/internal/handler/favorite.go, api/internal/router/router.go) [1] [2] [3]

Supporting Changes

• Updated MinIO client with helper methods for uploading and retrieving objects, simplifying file operations. (api/internal/minio/minio.go)
• Updated imports and configuration throughout the codebase to support new dependencies and injected services. (api/internal/router/router.go, api/internal/handler/project.go, api/internal/handler/instance.go) [1] [2] [3]

These changes collectively provide a robust foundation for handling user and project images, file uploads, and favorites management in the application.

Closes #12
