It displays a run header with link to web UI, like starting a new plan does, then confirms the run and streams the apply logs. If you can't apply the run (it's from a different workspace, is in an unconfirmable state, etc. etc.), it displays an error instead. Notable points along the way: * Implement `WrappedPlanFile` sum type, and update planfile consumers to use it instead of a plain `planfile.Reader`. * Enable applying a saved cloud plan * Update TFC mocks — add org name to workspace, and minimal support for includes on MockRuns.ReadWithOptions.
