Make pending payment state and dust exposure available to callers so they can inspect stalled payments and assess force-close risk. Also expose the maximum splice-out amount to help plan withdrawals.

Expose the same information through Rust and the language bindings.

Rust and UniFFI checks, unit tests, the new integration test in both configurations, doctests, and binding generation pass. The full integration run had two failures in existing tests. Both passed in isolation, but channel_full_cycle_force_close_trusted_no_reserve failed again with Bitcoin Core RPC at tests/common/mod.rs:632. Its clean-main run passed, so the cause remains unresolved. UniFFI rustdoc also fails on three broken links reproduced on main.

Fixes #1102
