Is the deferred dower considered a debt upon the deceased husband that must be paid to the wife from the inheritance, given that consummation did not occur?

It is permissible for the dowry to be prompt and deferred, or for part of it to be prompt and part of it deferred. If it is deferred and its term is not specified, it becomes due upon separation, whether by death or divorce. If one of the spouses dies before consummation, the woman is entitled to the full dowry. The deferred dowry then becomes a debt owed by the deceased husband and must be paid from his estate before it is divided among the heirs.
