Spend received silent-payment outputs (taproot key-path)
buildTx now includes received SP outputs in the coin pool, and sign() spends them
as taproot key-path inputs signed manually with d = spend_priv + t_k (the output
key is used raw — no BIP-341 tweak — so btc-signer's auto key-path signing
doesn't apply; we set tapKeySig from preimageWitnessV1 + schnorr.sign). The fee
estimator is fed a tapInternalKey (sizing only) with disableScriptCheck. SP value
folds into the displayed balance. Paying an sp1… recipient still uses BIP84 coins
(SP-input-funded SP sends need even-Y handling, deferred).
Validated on regtest via testmempoolaccept: a wallet-built, wallet-signed spend
of a received SP output is accepted by Core.
