Feature ETP-3641: Add API Changes related to CRM Connector features

[RomanMagnoli]

This pull request updates the developer changelogs (both English and Spanish) to document the complete removal of the CRM Connector from the core product, including all related database tables, columns, and Java event handler classes. The documentation now provides detailed guidance for developers and custom module maintainers on which entities have been removed and what actions are required before upgrading.

Key changes include:

Database Schema Removals:

• Removed all CRM Connector tables (C_ExtBP_Config, C_ExtBP_Config_Property, C_ExtBP_Config_Prop_Opt, C_ExtBP_Config_Filter, C_ExtBP_Config_Filter_Opt) and their associated Hibernate entities and Application Dictionary entries. [1] [2] [3] [4]
• Removed CRM-related columns from AD_Org (C_Extbp_Enabled, C_Extbp_Config_ID) and AD_ClientInfo (C_Extbp_Config_ID). [1] [2] [3] [4]

Java Class Removals:

• Deleted event handler classes in the org.openbravo.event package related to the CRM Connector: ExternalBusinessPartnerConfigColspan, ExternalBusinessPartnerConfigFilterEventHandler, ExternalBusinessPartnerConfigPropertyEventHandler, and ExternalBusinessPartnerConfigurationEventHandler. [1] [2] [3] [4]

Documentation Enhancements:

• Added explicit warnings and upgrade instructions for custom modules that may reference any of the removed tables, columns, or Java classes, emphasizing the need to update or remove such dependencies before upgrading. [1] [2]
• Linked to the relevant pull request (PR #977) for further technical details in both language versions. [1] [2] [3] [4]

This section introduces a second "### Database Schema Changes" heading (there is already one earlier in this same document) and later also repeats "### Removed Java Classes". Duplicate headings can create ambiguous/unstable generated anchors in the site TOC and make it harder to link to the right section. Consider renaming these headings to include the release scope (e.g., "25Q4 Patch – Database Schema Changes" / "25Q4 Patch – Removed Java Classes"), or nesting them under a unique parent heading for the CRM removal section.

Aquí se introduce un segundo encabezado "### Cambios en el esquema de base de datos" (ya existe uno antes en este mismo documento) y más abajo también se repite "### Clases Java eliminadas". Los encabezados duplicados pueden generar anclas/IDs duplicados o poco claros en el TOC del sitio y dificultan enlazar a la sección correcta. Considera renombrarlos incluyendo el alcance de la versión (p. ej., "Patch 25Q4 – Cambios en el esquema…" / "Patch 25Q4 – Clases Java…") o anidarlos bajo un encabezado padre único para la eliminación del CRM.
