Segmentations tools does not list segmentation models read from file or created w/o opening GUI

[Elaine Meng]

If I used "segmentations create" to create new segmentation models and then separately (e.g. from the menu) open the Segmentations tool, the existing segmentation model(s) I just created are not listed in the tool.

Similarly if I opened RIDER chest DICOM that already includes some segmentations, these segmentations aren't listed in the Segmentations dialog either. These SEG models used to be shown in the Segmentations dialog at some point and you could then edit them further, but maybe bit rot removed this feature.

session that includes SEG models included in original DICOM data, as well as segmentation added with "segmentations create" and two more from Add before saving

Attached session has SEG models #1.1.2-4 from original DICOM, plus one added with "segmentations create", plus two segmentations added with Add button on Segmentations tool. Before I saved the session, these two segmentations were listed in the Segmentations tool. But now when I restore the session, none of them are listed in the Segmentations tool. It totally lost track of what segmentations are existing and available to edit.

tested and session created in UCSF ChimeraX version: 1.9.dev202405090425 (2024-05-09)

the "read from file" was a previous old ticket #9526 that I reopened, so this ticket can just be for the other situation, created with segmentations command before opening the GUI tool in a separate step.

Should be fixed in ​this commit. The bundle now tracks segmentations independently of the tool, and the tool reacts to the data structure that tracks segmentations and its triggers.
