Performance and settings updates: - Add a new jellyfin_library_mappings column to the settings table and wire it into the Settings model (update handling and default value). This enables storing Jellyfin library mappings in settings. - Optimize Cast::list by loading all cast filmography in a single joined query and grouping results per cast to avoid N+1 queries. - Remove per-item cast/staff loading in Media model to avoid repeated queries during list/search operations. - Remove game-specific enrichment from MediaController search to stop extra game info lookups during search responses. These changes reduce repeated DB calls and centralize Jellyfin mapping storage.
