feat(job-array-single-wal-record): build the compact API-server push

Browse source 
Adds apiserver_push_jobarray() (apiserver.c), mirroring task 5.1's
xcesched_push_jobarray() exactly: same (base jobid, array_size, one
spec) Data.jobArray derivation, same direct xce_request()/OPCode_push
transport. apiserver_job_new_fun() branches on l->count > 1; the
existing single-job path (apiserver_push_joblist()) is byte-for-byte
unchanged.

Additionally, and unlike the scheduler (single target), replicates
apiserver_push_joblist()'s existing per-connected-server fan-out loop
(N_APISERVER_MAX iteration, same lock discipline) -- verified against
2 simulated connected servers, each receiving exactly one push.

New standalone apiserver_push_unit_test binary (same link-collision
rationale as task 5.1's sched_push_unit_test), correctly omitting
egress.c since apiserver_push_joblist() has no WAL-commit filter.

Task 5.2 of job-array-single-wal-record (Requirements 6.2, 6.4).

# job-array-single-wal-record task 5.2: apiserver.c's push logic
# (apiserver_job_new_fun / apiserver_push_jobarray) faces the identical
# real-vs-fake link collision task 5.1 hit for sched.c (test_commit_barrier_
# reply.c / test_worker_join.c already define their OWN fake notify()/
# on_scheduler_join(), so linking the real dataex.c into controller_unit_test
# collides at link time) -- so this is its own standalone binary too,
# mirroring sched_push_unit_test's strategy. UNLIKE sched.c, apiserver.c
# never calls job_submit_committed()/collect_jobs_committed() (egress.c), so
# this binary does NOT need egress.c -- verified by grep, not assumed
# identical to sched.c's dependency set.
