Fix crash when opening and closing Indirect Data Reduction multiple times #37410

Description of work

This PR fixes a crash when you open Indirect Data Reduction, close it, and then open it again. The presenter for the ISIS Energy Transfer tab was not being destructed because the presenter was being held as a raw pointer. This meant that the when a working changes in the ADS, the OutputOptions held by the presenter were trying to update the widget in the previously deleted interface. The solution was to use a unique_ptr to hold the presenters for the Data Reduction interface.

This PR does two additional things:

  • It ensures the OutputOptionsPresenter uses the ADSObserver class rather than implementing Poco observers itself. This is clearer to read, and ensures the same presenter does not subscribe to a poco observer more than once (this can cause issues as seen previously in Fix crash due to subscribing observer twice to notification center #37074
  • It ensures the Data Manipulation interface uses unique ptrs to hold their presenters. The crash was not being seen on Data Manipulation because the presenters are QObjects, and get destructed when the parent widget is destroyed

To test:

  1. Open Indirect Data Reduction. Close it. Open it again
  2. No crash!
  3. Also try the instructions in the attached issue

This does not require release notes because I believe this was introduced recently when IETPresenter was made to be qt-independent
