feat(statics): add Pearl (PRL) to statics and utxo-lib networks

Pearl is a Taproot-only UTXO chain (btcd fork) using BIP-340 Schnorr
signatures and BIP-341 script-path spending with a NUMS internal key.

- Add CoinFamily.PRL and UnderlyingAsset.PRL to base.ts
- Add Pearl/PearlTestnet network classes (bech32m HRP: prl/tprl)
- Add prl/tprl coin entries to utxo.ts with MULTISIG + BULK_TRANSACTION
- Add pearl/pearlTest to utxo-lib networks with Taproot + SegWit support
- Add isPearl() helper and update supportsTaproot()/supportsSegwit()
