Add debouncer to author searching while editing a book(s)

[noaione]

Describe your suggested feature

The route: /api/v1/author/names are currently not put in debouncer which make a request every time I typed something.

Adding 500ms debouncer (like the other route) should hopefully slow down the request to the server and improve performance a bit.
