kolaente 5dead874d2 refactor(background): extract download + unsplash-proxy logic for reuse ... Split the HTTP plumbing from the business logic in the v1 project-background download and Unsplash image proxy handlers so /api/v2 can reuse it without duplicating it: - LoadProjectBackgroundForDownload (background/handler) loads the bg file + modtime and fires the Unsplash pingback; GetProjectBackground now calls it. - WriteProjectBackground (web/files) writes v1's exact background wire shape (image/jpg, no-cache, stat-modtime Last-Modified, If-Modified-Since 304). - FetchUnsplashImageByID / FetchUnsplashThumbByID (background/unsplash) return the open upstream body for the caller to stream; the v1 proxy handlers now call them. A typed ErrUnsplashImageDoesNotExist maps to 404 on both APIs. - ErrProjectHasNoBackground (models) gives the no-background case a domain error; v1 keeps its verbatim 404 message. v1 responses are unchanged on the wire.		2026-06-12 11:51:52 +02:00
