feat: allow address(0) for ETH deployment in ListaRevenueDistributor

- Remove require != address(0) checks in initialize() for autoBuyback/revenueWallet/listaDistributeTo
- Add address(0) guards in _distributeToken() and _distributeTokenWithCost() to skip transfers
- Remove require != address(0) from setter methods to allow resetting to address(0)

This enables deploying ListaRevenueDistributor on ETH where revenue stays in the contract
for manual cross-chain bridging instead of auto-distributing.
