sync upstream Grim: bump node + wallet, adapt tx_log_iter

Upstream Grim advanced past the fork base with a node + wallet version update
(b51a46b → its "node + wallet: update to latest versions"). Bumped both
submodules (node → bce5a71, wallet → c2db754) and applied the one source
adaptation that update requires: `tx_log_iter()` now yields Result items, so the
three call sites filter Ok + unwrap before use. The upstream Tor/arti-0.43 commit
is skipped — Goblin removed Tor entirely.
