fix(gist): set gist subpaths individually to avoid CastError

Browse Source 
Mongoose treats `gist` as a nested path, not a sub-schema, so
set("gist", payload) mis-casts the inner subdoc arrays and fails
validation with 'Cast to [string] failed' at gist.files.0. Set each
subpath individually so the files/comments arrays cast correctly.
