This update adjusts how dropdown state is handled in the Gantt view, helping the interface behave more consistently. It is a small usability improvement for teams using planning or scheduling views.

Employees can now mark bank accounts as trusted from their employee record without requiring the account to follow IBAN formatting. This makes payroll bank account handling consistent across screens and better supports countries where non-IBAN accounts are common, such as the US.

When trusting a bank account from the employee's form view, a check was performed to verify that the bank account has a valid IBAN. This check is not performed on the bank account form view as a bank account (e.g. in the US) does not necessarily follow the IBAN format. This commits remove the IBAN validity check on the employee form view for consistency with the bank account view.
