This change expands Greek localization reporting with support for sending invoice data to the Greek MyData platform. It adds company settings, invoice fields, reporting templates, and tests to help businesses meet Greek electronic tax reporting requirements.

This fix resolves a memory error that occurred when installing the Argentine EDI module on databases with large numbers of accounting records. The solution optimizes how a specific field is initialized during installation, preventing the system from running out of memory during the process.

Issue -->

For a database with a large number of `account.move` records, the computation of the field `l10n_ar_fce_transmission_type` leads to a MemoryError when installing the `l10n_ar_edi` module.

Solution -->

Use the `_auto_init` method to add the column to the `account_move` table to skip computation during installation.
Set the value to NULL on init because the field does not have a default value.
