Fix groups in status updates

[AnandajithS]

Closes issue #70

This PR fixes the issue of groups shown in status updates and instead displays members by their tracks.

Thanks for the PR! Overall, it looks good with just a small suggestion.

I noticed that queries.rs hasn’t been changed in this PR, but I think it needs some updates related to this change -specifically, the query to fetch members is not fetching the track from root.

Thanks for the update! Just one quick request: could you squash the commits into a single one to keep the commit history clean?

Other than that, LGTM!

I wonder what will happen when a member does not have a track assigned to them, like for eg - first years. Wouldn't it just print "Track - "? We should probably have some logic to support this edge case.

I've made the required changes

• Updated the type of track to Option<String> to handle null values
• Added a match statement in format_defaulters to properly handle track

Looks good so far, guess we'll see if it works tonight :)
