This Fixes #12

@f8thl3ss dropping the cache RequestFull doesn't have a method property and props.request?.raw always returns the original request, not the user's edits. In replay, the editor is the source of truth since users can edit the GraphQL query/variables from the view mode and save changes back to the replay request. When the active editor switches to the response pane, we fall back to cachedEditorView (already existed for saveChanges) to keep reading from the request editor. This avoids losing edits without introducing any new caching mechanism.
