Delete orphaned attachments

[labkey-adam]

Rationale

Deployments have orphaned attachments. For now, we'll give admins the ability to review and delete them, if they wish. In the future, once we've confirmed our orphan detection is correct, we'll likely add an update script that invokes this.

Tasks 📍

• Dev
• Code review @labkey-matthewb
• Manual Testing / Verify Fix @DariaBod
  • Admin Console -> Attachments -> Click on any count to see details -> Customize Grid -> Show Hidden Fields -> Add "Orphaned" field -> Clear the ParentType filter -> Filter by Orphaned = True: you now have a list of all orphaned attachments in your server
  • If you don't have any orphaned attachments you can create some (on develop, as long as we haven't merged my fixes from 26.3) by:
    • Create a new user -> Edit profile -> Add an avatar -> Delete the user
    • Follow the ListItem orphaned attachments issue repro steps here: https://github.com/LabKey/internal-issues/issues/984
  • Invoke the core.deleteOrphanedAttachments() upgrade code: Admin Console -> SQL Scripts -> Upgrade Code -> Select "Core: deleteOrphanedAttachments()" -> Invoke
  • Upgrade code should execute without errors and your orphaned attachment grid should now be empty
• Needs Automation
