feat(ha-term-safety): restore controller build + wire vote/AE term wire fields (tasks 1.1, 1.2)

Browse source 
1.1: WalCatchupEntry gains term@4/prevLogIndex@5/prevLogTerm@6 (append-only).
1.2: RequestVote/PreVote gain lastLogTerm@4/lastLogIndex@5; cluster.c vote callers
fixed to the extended library arity (RESTORES xce_controller + controller_unit_test
compile+link, broken by the raft-commit-safety signature extension); ha.c emits the
candidate's last-log tuple on send.

5 minimal stub log/commit callbacks wired into s_real_cbs so raft_init's new
non-NULL requirement is satisfied — tasks 2.x replace them with real bodies; the
logOk freshness gate is inert until the term seam (1.3) + on_get_entry_term (2.2).

Pre-existing test_repl_unit.c wal_catchup -EAGAIN failures + ASAN leaks are an
overlayfs /tmp fsync env artifact (bug-850), not from this task (untouched paths;
append-only schema cannot affect the @3 entries-list decode). Build/baseline
isolation is blocked by a c-capnproto flake-hash drift — see Implementation Notes.
