Widgets: remove Event Countdown (dots) + Tasks Done Today (KC-17)

Drop the dot-grid EventCountdownWidget and TasksCompleteWidget from the
gallery: widget structs, their views, the todayTaskCompletion() helper
(only consumer), and bundle registrations. Shared event plumbing
(EventConfigIntent/Provider/Entry, CycleCountdownUnitIntent) stays for
the surviving Event Countdown (Bars); DotGrid stays for Day Progress.
Remaining widgets untouched.
