feat(jobs): Sub 14 polish — workflow state form layout + Simple Editor field

Two follow-ups on the workflow state work:

1) Form layout
   The "How triggers combine" help text was crammed into a 2-column
   group, taking ~25% of the available width. Pulled it out of the
   group and rendered as a full-width <div class="alert alert-info">
   below the trigger fields. Same fix applied to Notes — uses a
   <separator> + bare <field> for full sheet width.

2) Simple Recipe Editor support
   The trigger field was only exposed in the Tree Editor. Added it
   to the Simple Editor's inline library form too:

   * fp.step.template.triggers_workflow_state_id (new Many2one) —
     per-template default, snapshot-copied to recipe nodes when
     dropped into a recipe (added to _SNAPSHOT_FIELDS).
   * /fp/simple_recipe/workflow_states/list — new endpoint to feed
     the dropdown. Soft-fails when fusion_plating_jobs isn't
     installed (returns []).
   * Library editor JS — _fpEnsureWorkflowStatesLoaded helper
     caches the catalog on first open (create + edit paths both
     warm it). Save vals carry the trigger id.
   * Library editor XML — dropdown rendered after the flag
     checkboxes. Hidden when the catalog is empty so the form
     doesn't show a useless "— None —" pick.
