feat: multi select books and update book type

[vbh]

• Adds multi select option in menu options
• Select multiple books in both list view and grid view
• Update book type for the selected books from all the tabs

This PR does not implement checking the common book type of all the selected books and show it by default in change book type model.

Grid View	List View

@vbh Just tested it. I like the idea! My points:

• can you get rid off the "multi select" button? so the feature is enabled on long press?
• would be nice to have other edit options as well. I think editing author, status and deleting books would fit there too.

@mateusz-bak Removed multi select button. Regarding other options, I'll try to do it in a separate PR when I get some time.

Looks good, just one thing:

updateBookType in book_cubit.dart line 120 should also call getAllBooksByStatus(); for the book lists to reload.

I'll merge this PR and change. Awesome work, thanks!
