The previous asynchronous approach did not work particularly well, leading to large janks when switching to custom maps or opening the mission browser. This commit introduces two key changes: * Rule loading for WorldActorInfo and PlayerActorInfo is made synchronous, in preparation for the next commit which will significantly optimize this path. * The full ruleset loading, which is required for map validation, is moved to the server-side and managed by a new ServerMapStatusCache. The previous syntax check is expanded to include the ability to run lint tests.
