DRYD-2117 Procedure/Object > Ability to set Priority Image - top media priority image as search results thumbnail

[spirosdi]

What does this do?
It includes two changes, to make search-result thumbnails be populated according to the media priority order (along the current way). The changes are:

• In AdvancedSearch.java, check if a collectionobject has a media priority list and pick the top entry as the thumbnail in search results. If the list is empty, the endpoint falls back to the existing behavior.
• A new event listener UpdateMediaPriorityOnDelete, that removes entries from media priority list when the media record is unrelated or deleted.

Why are we doing this? (with JIRA link)
This is requested in the scope of the https://collectionspace.atlassian.net/browse/DRYD-2117. The record at the top of the Media priority should be the image shown in the grid and detail-list search result views. The listener is added to avoid showing unrelated/deleted media records as thumbnails. https://collectionspace.atlassian.net/browse/DRYD-2141

How should this be tested? Do these changes have associated tests?

1. Create a collectionobject related to two or more media records (with blobs), and set the Media Priority order so the top record is not the alphabetically-first one by title.
2. Search for the object in the staff UI. The grid and detail-list thumbnails should show the top-priority record's image.
3. Search for an object with related media but no priority list. The thumbnail should be unchanged (legacy title-sort behavior).
4. Unrelate the top-priority media record. It should disappear from the object's Media Priority panel, and the thumbnail should shift to the next entry.
5. Delete a top-priority media record. Same result to unrelate.

@spirosdi hopefully will be able to test this before the end of the day, if not I'll have to tomorrow morning. I left a few comments just from skimming things over, though everything seems good at a glance.

Would it make sense to use the media refname here (subjectRefName or objectRefName)? Then below we could do updatedList.remove(mediaRefName) or updatedList.removeAll(List.of(mediaRefName)) if we're concerned about possible duplicates.

thanks, done!

We have the CollectionObject csid already so we can reuse it here.

Tested behavior and verified the following:

• Object with multiple related media have deleted csids removed from the media priority list
• When deleting media for an object with a single related media it has no media priority after
