Add task title editing/deletion, timeline click-to-open, widget app launch

Task-detail modal was description-only with no delete affordance;
HandleUpdateTask now saves the title too and a Delete button hits a new
DELETE /tasks/{id} route backed by store.DeleteNativeTask, which repairs
chain_position/unlocks the successor when the deleted task belongs to a
chain. Timeline tab task/card/gtask rows now open the same detail modal
as the Tasks tab. Android widget's "TODAY" header is now a tap target
that launches DashboardActivity, since nothing previously opened the
full app from the widget.
