fix(timeline): include overdue native tasks in timeline and widget

GetNativeTasksByDateRange's SQL bound (due_date >= start) excluded any
task overdue from a previous day before ComputeDaySection ever got a
chance to mark it IsOverdue, so both the web Timeline view and the
widget API (which both call BuildTimeline with start = today) silently
dropped overdue tasks entirely -- only the Tasks tab (unbounded
GetNativeTasks) showed them. Added GetOverdueNativeTasks and folded its
results into BuildTimeline alongside the ranged fetch.
