[IMP] account_asset: extensibility
[IMP] account_asset: extensibility

Before this commit, it was not easily possible to add the seamless closing
workflow while having 2 or more depreciation boards (eg. according to accounting
standard). With this commit, I can construct the move lines independently
inherit properly and pass all created move lines to the window action.

Closes #16073
