How to use dax to implement the list.date function in the M function, just like the question require

Yes I know it's fake data, I just wanted to know if the amounts were correct without having to calculate them (they're not).

OK, first create a Dates table which covers all the dates in the model (so from earliest award start to the latest award end).

Then, in the first table, create 2 columns. One for the number of days between start and end.  The other for the amount per day (a simple division).

Then create a table with DAX:

GENERATE (
        Table1,
        DATESBETWEEN ( Dates[Date], [Award start], [Award end] )
    )

That should do it.

Now, having said that, with your real data, you should consider a Power Query solution to get the data compression OR maybe use measures to produce any final visualisation because the model is going to get big very quickly.
