[IMP] account: improve the onboarding

Task 2031686

* Change some labels on the dashboard
* Move the action "Take money In/Out" to a button because it was also dsplayed in bank journals and we only want it for cash journals
* Add reconciliation param on the first account config list, as well as a button to go to the form (it is an editable list)
* Add an action to duplicate accounts in batch
* Smartly detect when a cash statement can be extended instead of creating a new one, making it more obvious to the user that he may need to validate his previous statement(s)
