fix(wot): scrub NaN/inf in doodad/WMO placements at save time

Browse source 
nlohmann::json serialization throws on NaN/inf floats, which would
abort the entire WOT save and leave the user with an unsaved zone
state. Scrub on the way out so a single corrupted placement can't
take down the whole save.
