* Fix Ctrl+Enter losing amount value when adding transaction
Fixes#6901
When using Ctrl+Enter to add a transaction immediately after typing
in the amount field, the value wasn't being committed before the
transaction was saved, resulting in a zero amount.
The fix wraps the add-and-close logic in an afterSave() callback
to ensure field values are committed before adding the transaction.
Added regression tests for both debit and credit fields to verify
the fix works correctly.
