Clicking Settings → Rescan restarted the daemon with -rescan correctly, but the
progress poll fired "Blockchain rescan complete" the instant it was clicked,
then showed nothing for the entire (multi-hour) rescan — so it looked broken.
Cause: the very first getrescaninfo poll runs before the daemon has restarted
and hits the still-running pre-restart daemon, which answers rescanning=false.
The completion branch took that as "done", cleared the rescanning flag, and the
real rescan then ran invisibly. (Confirmed from a Windows debug-log capture: an
instant OK{"rescanning":false}, then ~6400 warmup errors over ~5h, all swallowed.)
Fixes:
- Gate completion on a new rescan_confirmed_active_ flag that's only set once we
actually observe the rescan running, so a pre-restart rescanning=false can't be
misread as completion.
- While the daemon is in -rescan RPC warmup it rejects every call with the live
phase as the message ("Loading block index..." -> "Rescanning..."). Treat that
as proof-of-progress: surface it as rescan_status and mark confirmed-active,
instead of silently swallowing it. The status bar keeps its animated
"Rescanning..." for the whole run, then reports complete when warmup ends.
- Read rescan_progress whether the daemon returns it as a string or a number
(the get<std::string>() would have thrown on a numeric field).
