refactor(events): remove dead specific-date filter logic

With the DatePickerStrip gone, selectedDate/selectDate in useEventFilters
were unreachable — nothing set a specific date anymore (the calendar page
only navigates to event detail). Delete the orphaned DatePickerStrip
component and strip the now-dead date-filter branch, state, and actions.
The feed filters purely by temporal pills + past/upcoming + categories.
