Second review follow-ups:
- Saving returns once the choice is stored; a send already under way picks up
the newest change, or the background retry is woken.
- A problem report still being sent when its address is removed is logged as
<removed>, checked under the same lock the removal holds.
- The prompt re-checks the privacy notice after fetching its state.
- docs/privacy.md: offline contact changes are sent later by themselves; the
prompt never follows straight after the privacy notice.
