("client: drop monkey-patch that is not mandatory anymore for NEO")

this restore the behaviour of the code before commit 8e073789

Also methods without a security declaration should not be added.

Rewrite Base_getPossibleWorkflowActionItemList by External Method instead of Python Script having a Manager proxy role.

because we loose existing roles in proxy role scripts and init scripts require Owner role in context.

because it is called from unrestricted method : builder._searchMovementList().

Avoid listbox with parameters from selection
