Bump LDK to 0.3-rc1

The 0.3-rc1 backports (rust-lightning #4937) include failing queued
splice contributions on ChannelManager reload and force-close
(rust-lightning #4918), which the upcoming splice tracking relies on: a
contribution dropped by a restart now replays SpliceNegotiationFailed
and DiscardFunding events instead of dying silently.

Adjust for rc1 API changes: HTLCLocator split into inbound and outbound
variants, and the async monitor reader dropped its _parallel suffix.

bitcoin-payment-instructions pins LDK by rev and must move in lockstep;
the previously pinned fork has no rev pinning rc1 yet, so the dependency
moves to an equivalent fork rev (the same tree plus the LDK bump).

Developed with assistance from Claude Code.
