This update refactors and cleans internal code for India reporting features, including GST returns, asset handling, and related configuration flows. It is intended to improve maintainability and reliability without introducing major visible changes for business users.

Technical improvement and cleaning up some stuffs :broom:

This update removes an outdated internal testing flag and adjusts related automated tests and safeguards across several Odoo Enterprise apps. It helps keep the platform aligned with newer core behavior while reducing maintenance complexity, with no expected day-to-day impact for business users.
