Expose wall-clock fire targets from the iOS NotificationInspector
(scheduled_time userInfo and predictive_<epochMs> ids) so the debug
panel is not misleading when nextTriggerDate resamples for interval
triggers. Extend TS types and show the scheduled target in the UI,
with a note when iOS nextTriggerDate diverges.
Make refreshPending a plain fetch so mock refresh, wakeup ping, flood
test, and clear notifications can refresh the pending list while an
outer withBusy guard is already active.
