feat(test-fakes): implement transfer_leader RPC on MemNetwork (#226)

MemNetwork implements append_entries / vote / full_snapshot but left
RaftNetworkV2::transfer_leader at its default, which returns "transfer_leader
not implemented". So Raft::trigger().transfer_leader() silently failed over the
in-memory network: the TransferLeaderRequest broadcast was dropped, and
leadership only moved when an automatic election timer happened to re-elect the
requested target. Multi-node harnesses asserting a *deterministic* handoff to a
specific node were flaky for exactly this reason.

Route the RPC to the target's public Raft::handle_transfer_leader, gated by the
same PartitionController reachability check as the other RPCs. Add a smoke test
that transfers leadership to a chosen non-leader node and asserts it takes over.
