This update reflects changes to Mexican withholding tax rates (ISR) mandated by the latest tax resolution. The update adjusts the ‘Mexico: ISR Table’ parameter in the Odoo system to align with the new tax tables effective January 1, 2026. This ensures accurate tax calculations for Mexican businesses using Odoo Enterprise.

According to the Mexican Tax Resolution (Resolución Miscelánea Fiscal 2026: https://dof.gob.mx/2025/SHCP/SHCP_281225_01.pdf), the ISR withholding tax tables applicable for the fiscal year have changed, effective January 1, 2026.
It is necessary to add a new parameter value for “Mexico: ISR Table” to reflect the new values.

This update prepares Odoo for Brazil's upcoming shift to a new consumption tax system starting in 2026. Users can enable this new system based on their business location and transaction types. The changes adapt existing tax calculation modules to comply with the new requirements, utilizing Avalara for tax processing.

2026 marks the start of Brazil's 8-year plan to migrate to a completely new consumption tax system [1]. The new system is meant to be simpler than the old one, but we defer to Avalara for tax calculation so we don't really notice it technically.

The old and new system have to coexist for the foreseeable future because the rollout happens gradually over many years. Whether the new system has to be enabled depends on the federal state the business is in, the type of transactions they do, and other factors. The user has the option to enable it through the l10n_br_is_icbs Boolean flag on the company, which gates all the new functionality.

These changes impact both tax calculation and EDI. This set of modules adapts our existing l10n_br* modules to the new requirements set out by Avalara. We are required to send extra values to their API, and in some cases adapt existing ones.

This update makes key JavaScript utilities within the 'pos_blackbox_be' module more easily accessible. By allowing these utilities to be imported into other files, the team can streamline future development and improve code organization. This change supports ongoing maintenance and potential enhancements to the point-of-sale system.

This commit puts export in front of some of the blackbox js utils/services/constants to make them importable from other files in the future.
