Electrum source: answer txStatus, so the replaced/evicted-tx pruner actually prunes.

_pruneReplaced only drops a pending row on a definitive "not found", and the
Electrum adapter had no txStatus at all — the call threw, the catch said
"transient", and nothing was ever pruned on the default data source. A
5,000-sat send the network never accepted sat in History as a pending
withdrawal for four days (and the cross-device union kept it fed).

Fulcrum's verbose transaction.get answers both halves: bitcoind's "No such
mempool or blockchain transaction" is the definitive miss (→ null), a
blockhash means confirmed. Other failures still throw.
