Show error message when attempting to withdraw from an org without permission

[john-light]

If an account attempts a withdraw from the Finance app of an organization without the permissions to do so directly or by vote, the withdraw window closes without giving the user an indication as to why the withdraw isn't going through.

Could be shown in the notification panel: #117

@john-light The panel should definitely show up with a "you can't perform this action".

[sohkai]

@john-light Ahh, actually reading this again, is this more about optimistic UI / notifying users that their transfer is "in progress" (in another app) rather than a user not having permissions at all?

[john-light]

@sohkai no, I am referring to the case where the user has no permission path to complete the transfer.
