flowmanager: add workspace endpoints for resolved types rename NestedType-/JsonDefinition to CustomTypeDefinition/ResolvedCustomTypeDefinition

This reverts commit 6ec0d630.

add types endpoint documentation to openApi.yaml and FlowManager.md; change "workspace_id" of typeDocuments to "workspaceId" to be consistent with other types.

make use of webutils.HandleError where applicable, refactor IsAuth and add the UserInfo to the Context

Auth middleware: make sure to ctx.Abort() when the the authentication fails, so other handlers won't be called

- Wrap errors instead of using `errors.New` so the Cause/Stack is accessible upstream
- optimize imports
- go-fmt project
