feat(widget): tap event to open its source directly, drop detail popup

Tapping a calendar event (or any event-type item) now opens the event's
URL (Google Calendar, Plan to Eat, etc.) directly instead of showing an
intermediate popup with an "Open in Calendar" button. Removes
EventDetailActivity and the recurrence-schedule lookup it was the only
consumer of: WidgetRepository.getRecurrence, the Go
/api/widget/recurrence endpoint, HandleWidgetRecurrence,
GoogleCalendarAPI.GetRecurrenceRule, and formatRecurrence, plus their
tests. RecurringEventID itself stays -- it's general calendar-sync
metadata used elsewhere in the timeline pipeline, not exclusive to the
removed popup.
