Fix regressions in roster-only suites from A06/A07/P14-03

The formal collector's roster includes 46 suites the Makefile never ran;
the first formal attempt stopped on test_required_kitchen and a sweep found:
- v15 MIMI purchase saves could not be written once Runtime saves carried
  mana_reserve (P06-01): the format detector now validates that section and
  excludes it before the unchanged v15 allowlist, like special_peeping_rooms.
- test_required_kitchen's legacy14 exact-load comparison now maps the two
  approved migrations (fresh A06 reserve at the restored boundary, elevator
  snapshot v1->v2) after checking each against its contract, in Runtime key
  order; every other byte must still match.
- test_runtime_defense_autonomy allowed Mana to change only by the A06 flow.
- test_p08_normal_placement_ops expects 25 palette slots (two warps); its
  suite-policy pin is updated with flags unchanged.
