An adaptation of the venerable business memento from 8.0 to the new
inventory valuation mechanics of Odoo 19.0 by scavenging and cobbling
together of the scripts `entries.js` and `coa-valuation.js`. The shared
data is kept in a separate file.
Additionally, we remove the old inventory valuation documentation.
