This update combines the Mexican reporting modules into a single, streamlined package. This simplifies maintenance and installation for users needing Mexican accounting reports, ensuring consistent reporting across the Odoo Enterprise platform. It maintains existing functionality without impacting current operations.

This PR merges the `l10n_mx_reports_closing` and `l10n_mx_xml_polizas` modules into `l10n_mx_reports`, as they all provide Mexican accounting reports and are required for standard reporting flows for any company.

This consolidation keeps all existing features unchanged while simplifying module maintenance and installation.
