Fix stale notification count and add deeplink navigation

Evening check-in no longer embeds the urgent task count in the body —
repeating notifications bake that value at schedule time so it always
shows a stale number. Replaced with a generic prompt.

didReceive now routes notification taps via ShortcutHandler:
'workout' deeplink → Workout tab, everything else → Today tab.
