0048645: The LastOrderComplete property should be removed from the application state

Description

The size of the application state has a big impact on the performance, as bigger states results in its persistence taking longer, and also on more frequent garbage collection runs.

We are currently storing in the LastOrderComplete property of the state the full object that represents the last completed order. This means that any time that any property of the state is updated, that order will be loaded into memory and then persisted again, unmodified.

We should remove that property of the state. If it cannot be removed (i.e. because some component listens to changes done in some part of it), we could leave that part in the state and remove the rest, that would be loaded only when necessary (i.e. on an action preparation or a useEffect hook)

Steps To Reproduce

In the terminal where this problem was reproducible, the average duration of the addProduct task went down from ~400ms to ~230ms after cleaning up the state. This included not only the LastOrderComplete property but others too.
