Inconsistent 'Last Updated' and 'Last Deployed' timestamps against instances

### Current Behavior

In various views we display an elapsed time (`one week ago`) to indicate activity.

We have two different values
- `Last Updated` - which reflects the `updated_at` field of the database object
- `Last Deployed` - which reflects the last time the flows were updated (via the `Storage` table)

We are not consistent in their use and in some places I think we are mislabelling one as the other.

We should pick one and use it consistently.
