Use ldk-node's new splice_in_with_all and open_channel_with_all APIs, which compute the maximum drain amount net of fees and anchor reserves. This replaces the hand-rolled fee subtraction on splice and the hardcoded fee constant on channel open. Drop the amt parameter from the LightningWallet trait's open_channel_with_lsp and splice_to_lsp_channel methods. Every implementation discarded it; the signature now matches the contract.
