This update fixes inaccuracies in how tax amounts are calculated for Arabic VAT transactions. By modernizing the calculation engine and ensuring precise formatting of final amounts, the system now delivers more accurate VAT reporting and financial figures. This improves the reliability of financial data within the Odoo Enterprise system.

- Rewrite all tax amounts calculations on `_get_tributes` and `_get_line_details` to properly use the tax computation engine helpers (`base_line`, and aggregating methods)

- Ensure that all final amounts from the calculation are formatted with `float_repr` with appropriate precision.
