[ER][<Deadlines>]: Enhancement

[AdamPiotrowski91]

Current State: (details of what we currently have, if applicable to this ER) Items are considered closed when they are completed throughout the architecture of deadlines

Description of New Functionality: (details of what and how should work) It seems when US is Completed but not Accepted, there's still potential actions to be taken for the process of accepting

Additional Context & Ad Hoc Info: (Add any other context about the request here.) Need to either

• [x] Not consider US "done" when Completed (and retest all other features dependent on this behaviour)
• Rework Deadlines so that they can always be added (and therefore rework clean-up architecture for them)
• potentially BOTH

To be done for 3.4 at the latest. Consider rescheduling for earlier.
