style: rustfmt the freeze-until-reanchor client wiring

cargo fmt --all --check flagged the reanchor gate wiring (decode.rs / session.rs /
abi.rs / reanchor.rs): wrapped signatures + comparisons, and two multi-line comments
that followed a trailing-comment line were restructured to their own lines so
rustfmt keeps them at normal indentation instead of deep-aligning them.
