"""D5 last pass: the endpoint table (call-id -> URL), CreatePack's URL builder,
who sets the CreatePack purchase MODE, and the PurchaseItems response defaults.

HYPOTHESES
 H9: every FUT ServerCall carries a numeric id (CreatePack=0x4b, PurchaseItems=0x4c,
     passed to FUN_18016be60) and a table near 0x18021e100 maps id -> URL format
     string ("ut/%s/store", "ut/%s/purchased", ...).
 H10: FUN_180124ad0 is CreatePack's URL builder and it emits the "store/transaction"
     path we already see on the wire.
 H11: the mode field at +0x20 of the CreatePack call (0=COINS,1=MTX,2=POINTS,4=preorder)
     is set by whoever constructs it; callers of FUN_1801623d0 will show the choice.

CONTROL: dec(0x180162530) reprinted (known: writes packId/useCredits/usePreOrder/currency).
