feat: implement job state, queue state, and worker recovery in WAL replay

WAL payloads:
- Job state transitions (START/FINISH/FAIL/STOP/RESUME/UPDATE etc):
  wal_jobstate_t {uint64_t jobid, uint32_t state} — restores exact state flags
- Queue state (QUEUE_CTRL): wal_queuehdr_t {uint32_t status} + name string —
  re-applies admin open/close/active/inactive after config queues are built
- Worker CTRL: existing [uint32_t detail][capnp xce_worker_t] unchanged

New recovery functions:
- restore_job_state(c, jobid, state): looks up job, overwrites state flags
- restore_queue_state(c, name, status): looks up queue, overwrites status

apply_wal_entry: dispatches all WAL types including job state and queue
test_repl_apply.c: weak stubs for restore_job_state/restore_queue_state
  so unit test binary links without job.c/queue.c
