cmd/relui: generate uuid for workflow and task instances

Sets workflow and tasks IDs when a workflow is created in the UI. These
IDs will be used in the future when operating on workflows and tasks via
the UI or API.

This ID will likely change to a datastore ID after datastore integration
is added.

For golang/go#40279
