Fixed — services/web-ui/nginx.conf now sets proxy_set_header Content-Type $content_type in the /api/ block so multer receives the full multipart boundary. Verified in current main.

Fix Plan — #74 nginx strips Content-Type for multipart uploads

Root cause: Multer's memoryStorage needs original Content-Type: multipart/form-data; boundary=... header. If nginx normalizes headers, multer fails with MulterError: Unexpected field.

Fix:

Add to nginx config:

proxy_set_header Content-Type $content_type;

Configure multer with explicit limits:

multer({
  storage: multer.memoryStorage(),
  limits: { fileSize: 500 * 1024 * 1024, files: 1 }
})

Files: nginx.conf, src/routes/upload.js
Effort: ~30min
**Priority: P2 — upload reliability
