fix(memories): route upload through server proxy to avoid R2 CORS failure

Browse source 
Direct PUT to R2 presigned URL is cross-origin, causing "Failed to fetch"
in browsers without R2 CORS configured. Use the existing PUT /api/upload
proxy handler instead — file goes client → Next.js → R2 server-side.
