FEAT: Add display name of database connection beside name from database structure tab

[stunited-thien]

Thank you for developing this awesome app, I have tried Table Plus, DBbeaver, and DbSchema but they didn't support MongoDB or only limitation of it

Is your feature request related to a problem? Please describe.
it's not technically a problem, but it is tedious since my current work needs to transfer data between databases that have the same structure including names but just different environments and version

Describe the solution you'd like
I would like to have another tab above that represents the name of the database and this tab will wrap any database structure tabs related to it, kind of like current database structure tabs that wrap its collections.

Describe alternatives you've considered
I know that when you select different database structure tabs, the Connections dropdown which is on the left sidebar corresponds by highlighting the name. But it doesn't scroll to the center for the highlight. Maybe you can update that so it can correspond to like how the table of contents on the web works
