Include issue identifier in all activity log details for notifications

Activity log events for issue.created and issue.updated were missing
the identifier field in their details, causing toast notifications to
fall back to showing a truncated UUID hash instead of the shortname
(e.g. PAP-47). Also includes checkout lock adoption and activity
query improvements.
