Pre-super: when finishing the last open step on an in_progress job,
run the bake/qty/QC gates from button_mark_done so failures surface
as UserError on the click (per spec D12). Without this the
auto-advance would silently fail with no error path.
Post-super: trigger _fp_check_advance_post_shop so the state
auto-advances cleanly (in_progress → awaiting_cert / awaiting_ship).
Added _fp_check_finish_gates helper on fp.job and a
fp_check_gates_only context flag honored by button_mark_done so the
gate logic is single-sourced (DRY).
