[andrabrinzaniuc]

WIP - @andrabrinzaniuc to provide Figma design

CONTEXT/USER GOAL
As an NGO admin, I want to add a service to the nomenclature of my organization. I select the type of service and I need to specify which interventions I would like to make available for my staff

ENHANCEMENT

• Re-organize the Select (checkbox) & activate (toggle) actions so the sequence of actions is more clear (select first, activate second)
• Add select all/ deselect all option for list of interventions, so that users can manage the list more easily (increased task efficiency)
