The birth place picker reported null on a failed timezone lookup and on a
half-chosen level; BirthLocationFields then cleared the place and the picker
reset its draft. Editing a saved person's date, time or place during a
timezone outage silently erased the birthplace with no error or retry.
The same path reset the picker when changing province/city/country on edit
and when opening an overseas person while the region list loaded.
- The picker only reports a freshly resolved place; failures and unfinished
choices keep the previous value and report "pending" instead.
- BirthPlacePendingScope + BirthPlaceSubmitButton disable 保存 (edit dialogs)
and 确定 (onboarding) while pending.
- Failure copy for a person with a place: 「时区这会儿没查到，原来的出生地还在，
查到后才能保存。」 with 重试; new profiles keep the existing copy.
- Track the moment the stored offset was resolved for, so going back to the
original date after a successful lookup re-resolves instead of saving a
stale offset; ignore late results from aborted lookups.
