Don't override user-defined Content-Type for GraphQL and form-urlencoded requests

The frontend already sets the appropriate Content-Type header when
selecting a body type, so the backend no longer needs to force it.
This allows users to override Content-Type for servers with
non-standard requirements.

Fixes https://yaak.app/feedback/posts/graphql-mode-ignores-manual-content-type-header-override
