Aggregate multi-host grouped summaries in categorized watcher posts

- update the categorized watcher to parse all ATVM host rows from a grouped Cloud Run Finished block instead of only the first host row
- allow a later terminal grouped summary to replace an earlier RUNNING state for the same logical group so grouped posts are emitted with the full host set
- fix multi-host same-group reporting so batches like ubuntu22.04 plus ubuntu24.04 are posted as one grouped result with both hosts included
