This demo-only change cleans up experimental search tool buttons so the example is easier to read and safer to maintain. It is not intended for inclusion in the main Odoo product, so business impact is minimal.

This is just demo code and should not be merged with odoo. Details in the commit messages

This update removes an unnecessary variable from the account reports module that was redundant with existing functionality. The system now uses a single method to handle report exports, making the code cleaner and easier to maintain without any changes to how reports work for users.

The `export_report` variable is not longer needed since `dispatch_report_action()` is already handling it through the `on_sections_source` parameter.
