feat(endfield): track AIC Quota Exchange permits by banner rotation

The shop's five permits restock when the character and weapon banners change together, which no week, month or fixed cycle can express: rotations ran 21 days and then 19. A rotation is not a game version, so it gets its own table and caption, and follows the version rule that only a recorded end resets the count. The dates and reset rule are the owner's in-game reading, as no page states them.
