Account Bank Statement Partner Autofill

This module extends the behavior of bank statement line creation and reconciliation in Odoo.

• When importing a bank statement, if a line has the same payment reference as a previous reconciled line, the system automatically assigns the same customer (partner_id) to the new line.
• When a statement line is reconciled and has a partner_id set, all other lines with the same payment reference and no partner_id are updated automatically.

This feature avoids the need to manually assign the same customer each time for recurring bank movements that use consistent descriptions in the bank extract.
