### Issue before this commit:
When reversing an invoice with a credit note in the l10n_cz and l10n_sk only the invoice_date is updated with the reversal_date but not the TSD date.

### Steps to reproduce the issue:
1. Download Accounting and l10n_cz (same steps can be done for l10n_sk)
2. Go to invoices and put as not invisible the Accounting Date field
3. Create and post the invoice setting as Taxable Supply Date (TSD) a previous date
4. Create a credit note for the invoice with reversal date as today for example and then click Reverse
5. See the dates (as taxable supply date and accounting date) are not updated

### Cause of the issue:
Prior to version 19, the taxable_supply_date (TSD) was a localization-specific field and did not exist in the core account.move model. Consequently, when the reverse_moves method:

executed, the accounting date was recomputed but the TSD was left unhandled. Thanks to PR https://github.com/odoo/odoo/pull/225035, which natively integrates this field into the core account module in version 19, the fields are now properly aligned and the issue is no longer reproducible.

### Reason to introduce the fix:
The fix explicitly populates taxable_supply_date with the wizard's reverse_date during the reversal preparation process.
