Unmarking (or marking) a mining address didn't change the history. The refresh
re-scanned the affected transaction as "receive", but appendMissingPreviousTransactions
carries over not-yet-rescanned prior transactions and dedupes by txid+TYPE — so
the stale "mined" copy was carried over right alongside the fresh "receive", and
the change never appeared.
Re-label state_.transactions in setMiningAddress() the moment the flag changes
(mined vs receive is just whether the receiving address is mining-flagged). The
History tab updates instantly, and the next refresh's carry-over now matches the
fresh scan instead of duplicating the old label. The reclassified list is also
persisted via the existing cache save.
