Touchless Expenses Allows Submission with Disabled Account Combination Override

We have identified what appears to be a validation inconsistency in Touchless Expenses when users override the expense account combination.

Steps to Reproduce

1. Create an expense through Touchless Expenses.
2. Open the expense and override the account combination.
3. Enter an account combination that is disabled/invalid in General Ledger.
4. Create the expense.

Observed Behavior

• When you reopen the Edit Expense page, the accounting section displays an "Account isn't valid" error at the line detail level.
• On the main Expenses page (expense overview/worklist), no validation error is displayed.
• The expense can still be submitted despite the invalid account combination.
• Submission succeeds even though the expense line contains an account validation error.
