M: S16F7/F8 PRJobMonitor + S16F15/F16 PRJobCreateMultiple

Closes the two E40 bulk/control gaps the COMPLIANCE doc had flagged
as out-of-scope:

  S16F7 / F8   PRJobMonitor — host enables/disables S16F9 alerts
               per PJ.  PRALERT bit 7 is the enable flag (matches the
               ALED convention from S5F3).  Server dispatches into the
               existing set_alert() store API.

  S16F15 / F16 PRJobCreateMultiple — bulk create variant.  Host posts
               a list of (PRJOBID, PPID, MTRLOUTSPEC) entries; the
               equipment processes them in order and returns a
               per-PJ HCACK list so the host can identify which
               subset failed.  Same validators as S16F11.

Catalog now has three new structs: PRJobMonitorEntry,
PRJobCreateEntry, PRJobCreateMultiResult.  Two round-trip tests cover
the new wire shapes; server-side correctness is exercised through the
existing PJ store invariants (dedup, validator) which both new paths
delegate to.
