This update enhances the AI agent's understanding of Odoo's core models by introducing a dedicated 'explanation' field. This allows the AI to generate more relevant and detailed context for its operations, improving its performance and accuracy. The change impacts several key enterprise modules like HR and Sales, leading to better AI-driven insights.

This PR introduces a dedicated _explanation attribute to Odoo's core models and actions to provide verbose, LLM-targeted context. 

Previously the AI agent relies on the _description attribute, which in fact has little to do with action of describing. It just the human readable display name of the model. 

By adding a separate explanation field to `ir.model` and `ir.actions.actions`, we can now provide better explainability of the model for both ai and humans use.

This PR has introduced a selection of description. Future work should continue to add more in the future.
