Don't allow to scan books that are owned by other characters

[Demivan]

Summary

Bugfixes "Don't allow to scan books that are owned by other characters"

Purpose of change

Fixes #65840

It was possible to scan books from merchant inventory without buying them.

Describe the solution

Add is_owned_by check when selecting books for the list of books to scan, filtering out books that character does not have access to.

Describe alternatives you've considered

Keep displaying all books, but mark owned ones and allow stealing them when scanning.

Testing

1. Spawn Exodia base.
2. Check that books in merchant inventory are not listed for scanning.
3. Spawn a refuge center.
4. Check that books that you cannot pick up (would be stealing) are not listed for scanning.
5. Check that books in a library and in houses are still scannable.

Additional context

Seems like there is a similar issue with reading. It allows reading books in refuge center that the character cannot pick up, as that would be stealing.

Actually I would prefer this alternative, so that I can lure NPCs out and pirate their books without them knowing.

I think this is very silly. The value of the book is the physical print that doesn't need any power to be read, not its intellectual property. It is literally would cost the refugee center nothing to let you scan their books, and presumably survivors want to help each other survive rather than perpetuate one of the most arbitrary creations of capitalism. Nothing is actually being stolen. On the other hand the physical print of the book is the actual object that would be lost if you took it (they wouldn't have it anymore)

I think this suggests two solutions. One we assume that since books are highly valued as trade items that factions won't allow non faction members to scan their books. Or two we make books worthless outside of quests and broker actions and the freedom of information exists.

I vote for the first solution because it doesn't require us to rejigger the in game economy.
