Enable Offerings attached to Deactivated Programs to be edited ('Mass Offering Change' and 'Student Edit')

**User Story**
As a student editing their application after their program was deactivated, I want the deactivated program and all associated offerings to be selectable on their dropdown list, so that I can remain eligible to train out of my program.

As a Ministry user, I want to be able to edit an offering (i.e. 'mass offering change') within a deactivated program so that the offerings still in active use by students can be modified and remain up-to-date.

As a Ministry user, I want to be able to initiate a Request an Offering Change for a single student attending a deactivated program, and have the deactivated program still be selectable, and new offerings to be able to be created.

**Rationale for why these are low priority:**
- There is functional workaround that does not impact funding; school and/or student simply selects newly created 'replacement' program and offering.
- Low volume of impacted users
