Migrate all btcd dependencies to the new per-package v2 modules (wire/v2, txscript/v2, chaincfg/v2, chainhash/v2, btcutil/v2, psbt/v2, btcec/v2) introduced by btcd v0.26.0, and pin the tagged ecosystem versions: btcwallet v0.17.0, neutrino v0.18.0 and lightning-onion v1.4.0. The bulk of the import rewrite was produced by the scripted diff from https://github.com/btcsuite/btcd/pull/2547 (followed by 'make rpc'). The address symbols that moved out of btcutil into the new address package are imported as btcaddr where a local "address" variable would otherwise shadow them. The go.mod/go.sum updates and the remaining manual compilation fixes are folded into this single commit so it builds on its own (the migration was previously split into a reproducible scripted-diff plus follow-ups, intended to be squashed on merge).
