fix: unguarded future::get() crashed on render/floor-query worker exceptions

Browse source 
std::future::get() re-throws any exception from the async task. The 6
call sites in the render pipeline (terrain/WMO/M2 workers + animation
worker) and 2 floor-query sites in camera_controller were unguarded,
so a single bad_alloc in any worker would terminate the process with
no recovery. Now wrapped in try-catch with error logging.
