rpcclient: harden DisableAuth transport tests

This commit only changes tests and clarifies a public comment. It does not alter the actual authentication behavior of the btcd RPC client. The code already only suppresses the internally generated Basic auth header when DisableAuth is tru…

No functional code change; only tests and commentsComment clarification that DisableAuth only suppresses generated Basic auth, not caller-provided Authorization headersTests now cover WebSocket handshake, cookie bypass, and caller-provided headers

This commit fixes a deadlock risk in btcd's new Bitcoin v2 transport handshake. Previously, the responder waited until it had received the initiator's full 64-byte key before doing any work, which could cause both sides to sit waiting for …

psbt: decode base64 packets incrementally

This commit changes how btcd reads base64-encoded PSBT (Partially Signed Bitcoin Transaction) data. Previously, the code read the entire base64 input into memory before decoding, and it wrongly applied the Bitcoin P2P wire message size lim…

lnwallet/rpcwallet: accept zero-value WitnessUtxo entries in remote-sign prep
