The code behind delete confirmation messages in Account Reports was streamlined to reuse common behavior and use clearer internal wording. This should make future maintenance easier without changing the visible user experience.

- Share code of message deletion with `msg.showDeleteConfirm()`
- MessageConfirmDialog props are more neutral
- patch `shouldHideFromMessageListOnDelete` once per module

The batch payment functionality has been consolidated by removing a now-unnecessary bridge module. This reduces internal complexity while keeping the expected accounting batch payment features available through the main batch payment module.

There is no more reason to have 2 modules, 
as account_accountant is already auto-installed in enterprise. 
So we should not need this bridge module anymore.
