Migrate to tview as TUI library

Description

This project started out using gocui as TUI library but I quickly regretted that decision, since it's been 3 years since the last meaningful commit. At some point, I forked the library to add the tabs feature I used the database's metadata views.

At the beginning of the year I planned out to migrate the app to bubbletea, but I couldn't worked on it due to multiple reasons (personal and professional reasons), until now, but I didn't migrate the app to the library mentioned above because I found out that wasn't a good fit for the way dblab works.

Then. I came across a tutorial on tview and I considered it as a potential option for dblab. Finally, I read some tutorials on the matter and quickly found that they have a database client demo that could serve as the foundation layer of the migration to it.

The final object of the migration to a new TUI library is being able to add more modern and flexible features to the client, Gocui was very limited and the fact that was very outdated adds more to it. After landing this change we can scope out the addition of more ambitious features and more database management systems.

To accomplish the migration, this PR removes the gui package and adds a new one called tui. Also, it removes my forked library from the dblab's dependency graph and adds tview as new dependency.

Fixes #198
