Account Reconcile Model Multicompany Propagate

This module adds a way to share reconciliation models across companies in a multi-company database. On the reconciliation model form, a new button "Propagate to companies" appears for users with accounting rights. Clicking it copies the current model to every other company you have access to that uses the same chart of accounts template.

If a company already has a reconciliation model with the same name, it is updated in place; otherwise a new model is created. The module also shows an alert on the form when another company with the same chart of accounts already has a model with the same name, warning that it will be overwritten.

The propagation copies the main settings of the model (rule type, matching rules, amounts, partner matching, etc.) and also recreates the model's lines, linking accounts and taxes by their code or name in the target company. If an account or tax does not exist in the target company, that line is skipped and a warning is logged.

A server action "Propagate Reconcile Model" is also available from the list view of reconciliation models, allowing you to propagate several models at once. The feature is limited to users in the accounting group and only works between companies that share the same chart of accounts template.
