Implement a modern BSV wallet with HD derivation, WhatsOnChain integration, and nLockTime support.

This PR adds a BSV wallet featuring BIP39 seed generation, BIP32/BIP44 derivation, P2PKH addressing, and transaction building with configurable fees, change handling, BIP69 sorting, and absolute nLockTime. nLockTime is enforced by setting transaction input sequences to 0xfffffffe. Persistence for keys was intentionally omitted, keeping them in-memory.
