Fix: defeating the demon never granted the ring

curFloor() returns the *generated* floor object, which only carried
{index, rooms, byId, entryId, exitId} — not the config flags. So
`floor.final` was undefined on defeat, and the ring (and ring/win screens)
were never granted even after beating the Level -6 demon; keys still
accrued because they key off room.isBoss + floor.index, which is why you
could end up with 4 keys and no ring. Generation now carries the floor's
tier/label/boss/final/surface metadata onto the generated object. Also
name the final boss the demon (not a dragon) in the room title, description
and Face button.
