Adapt to lightning-block-sync HTTP layer migration

The latest LDK dependency bump replaced the custom HTTP implementation
in lightning-block-sync with the `bitreq` crate, changing constructor
signatures, error types, and response parsing constraints. Update the
bitcoind chain source to use the new string-based URL constructors and
structured error enums.

Use a dedicated BitcoindClientError type since std::io::Error was only
used previously because that was used upstream.
