Increase lore page count limit

Right now it’s not possible to have more than 100 pages in the in-game lore.

However, RAG applications are easily able to handle more than this. And for highly detailed worlds, more than 100 pages is necessary to accurately represent some things.

I’d recommend removing the cap entirely, and maybe just warning the user that after a certain amount of pages RAG can get a bit funky and less accurate (though in my experience this limit is fairly large esp. with today’s embedding models and agentic RAG).
