Proxy-pallet: Define deactivated & concluded status

[didiermis]

In the Adobe XD there are two states for a project that haven't been defined yet:

• Deactivated
• Concluded

What validations should we consider for each status? (when a project is deactivated no one can perform any actions on it, a project can't be concluded if it has active drawdowns, etc)

I don't think we need those steps for the current Phase. Let's move this to the backlog and remove the options from the UI
