[FEAT] Users' Library feature

Implement a user Library feature.

Use the current [Library] button in the left navigation drawer panel to implement a feature or set of features that allows the user to store the books they currently own.

Later on we can implement borrowed books, eBooks, PDFs, etc features as well as favorited books.

way the app is currently rendering, the view has a table with books. This was meant for displaying only when the user clicked on the "Library" button in the left side navigation panel drawer. This button clearly does not really do anything, nor is there a way to close this view and return to the global scope of the app showing all books added to the database.

The main app view should show not only books added to the users library but the apps' database(s). of books. A user could theoretically add a book to their library which has not been added to the app's global scope database yet.

(Note the view currently displayed is actually meant to display when the user clicks on the "Library" button in the drawer, thus showing the books in the users' own library or collection of books showing what they own.)
