Add prefix search to search by internal DB ID (#1856)

This prefix searches entries in the library based on the ID in the
database. It is a niche feature but could be very helpful in certain
situations, such as a corrupted cover causing a crash that just shows
"🚨 Failed - MangaCover(mangaId=2245, sourceId=1, isMangaFavorite=true, url=, lastModified=0)".
With this prefix search it is possible to find the entry in question
without much hassle.

Notably, the database includes literally anything Mihon has ever seen
from extension and such, even if they weren't added to the collection.
This means that IDs actually present in the collection are not
expected to be purely sequential.
For example, in my emulator, I had two entries in the collection but
the assigned IDs were 5 and 56.
