Rework the Characters and Scene Drawers

🚩 Is your feature request related to a problem? Please describe

The more people use Fari, the more content they have to manage.

That means that sometimes, simply listing their scenes and characters isnt enough for them to find exactly what they are looking for.

✅ Describe the solution you'd like

We should look into reimplementing the Manager component so that it has a similar feature set as the DataRoute such as searching for a specific item by name of group.

It was also mentioned on the discord server that we could also expand or collapse groups but I feel like it would just be a solution to the wrong problem

I think the main problem is that there's too much content and we need to find a way to show the most relevant content to the user.

A couple of weeks ago, a user mentioned having a folder like hierarchy where you first see all groups and when you click on a group, you see all items inside that group which is something that I really liked and could also be generic enough so that it would work for both scenes and characters
