test(job-array-single-wal-record): end-to-end fault-injection test for the live fence

Browse source 
New test_job_array_fence.c exercises the full Requirement 9.4-9.6
engage-refuse-clear-recover sequence through real production seams:
forced array-expansion failure -> fence engages -> promotion refused
at a real ha.c gate site -> zero partial elements visible -> a second,
independent node's progress is unaffected -> clearing the failure and
retrying self-heals the fence and re-opens promotion eligibility.

Deliberately drives this through task 3.1's construction-phase
(scratch-build) seam rather than the bulk-insert-phase seam: the
bulk-insert seam has a known, separately-tested residual gap (an
already-inserted element prefix can survive a mid-pass key_add()
failure with no key_del to undo it), so asserting "no partial set"
against it would misrepresent an already-documented open gap as
resolved. That gap remains open and unowned (see tasks.md
Implementation Notes) -- Phase 4 delivers the generic halt/fence/gate
machinery for it, not the partial-visibility guarantee itself.

Task 4.4 of job-array-single-wal-record (Requirements 9.4, 9.5, 9.6).
This completes Phase 4 (Live Apply Resource Fence).
