fix: fix all dev static/media serving issues

- Remove WhiteNoise from MIDDLEWARE in development: it intercepts /static/
  requests and serves from STATIC_ROOT, which is empty without collectstatic.
  Django's runserver serves static files natively with DEBUG=True.
- Switch to StaticFilesStorage in dev: no manifest required.
- Add media URL pattern in DEBUG mode: runserver does not serve MEDIA_ROOT
  automatically, so uploaded images were 404ing in local dev.
