Port monero-lws to wownero-lws

Adapts monero-lws for Wownero cryptocurrency:

- Rename all monero-lws-* binaries to wownero-lws-*
- Update submodule to point to official Wownero repo
- Use Wownero default ports (RPC: 34568, ZMQ: 34569)
- Update data directory to ~/.wownero/light_wallet_server
- Adapt next_difficulty() calls for Wownero API signature

Key technical changes for Wownero compatibility:

- BulletproofPlus (RCTTypeBulletproofPlus, type 8) commitment verification:
  Wownero stores BP+ commitments in 'divided by 8' form. Must call
  rct::scalarmult8() on outPk commitment before comparing with computed
  commitment (mask*G + amount*H). This is essential for amount decryption.

- Pass rct_type to decode_amount() for proper commitment handling

- Handle Wownero's ZMQ JSON format for ecdhTuple (32-byte mask/amount fields)

No fork of Wownero is required - uses official codeberg.org/wownero/wownero.
