feat(job-array-single-wal-record): gate promotion on the live apply fence

Browse source 
Threads !persist_apply_resource_fenced(&c->persist) as a required
conjunct into both existing promotion-eligibility call sites in ha.c:
the periodic fence-release check (promotion_fence_timeout_fn) and the
election-time check (raft_cb_become_leader). A node with the fence
engaged is refused promotion at both points; once it self-clears
(task 4.2), the node is eligible again with no other action.

Task 4.3 of job-array-single-wal-record (Requirements 9.4, 9.5).
