New wal_entry_type WAL_JOB_DISPATCH=12, reusing wal_jobstate_t verbatim
(_pad=0, absolute-value semantics), wired into both apply_wal_entry()'s
and apply_committed_entry()'s existing job-state fall-through groups per
Requirement 2.4. Restart-replay test writes only WAL_JOB_SUBMIT+
WAL_JOB_DISPATCH to a real on-disk WAL and confirms job.state==RUN after
a fresh persist_recover(), independent of WAL_JOB_START.
Review found apply_wal_entry() has zero production call sites today
(persist_recover() and standby catch-up both route through
apply_committed_entry() post the 2026-07-10 ha_apply_single_entry
refactor) -- design.md's stale characterization corrected; the dual
case-label registration itself is unaffected and correct.
