Proposed changes

Fixes #5356

This changes the editor API CORS middleware so OPTIONS requests for paths under httpNodeRoot can continue through to the HTTP node app when httpNodeCors is configured.

That lets HTTP In preflights use the methods configured in httpNodeCors, including PATCH, instead of being answered first by the editor/admin CORS middleware. The same deferral is applied to both the default editor CORS middleware and a configured httpAdminCors middleware.
