Description

Description

Currently we only have the investment_limit for asset investments, but it would be more useful to have a limit for the available units, i.e., considering decommissions.

Note this function can be realized after #1302, using group investment limits, as a workaround.

But if we choose to implement this feature directly, to me, it makes more sense to remove the asset investment upper bound, and use this investment_limit as the upper limit for available units. But then the name needs to be changed, because it is no longer "investment limit" but "available unit limit". That we need a discussion since it may touch other functions.

Contributor guide

Research direction
Examine the existing investment limit implementation and understand how group investment limits work after #1302. Then propose a plan to replace investment limit with available unit limit, ensuring backward compatibility and updating all references.
