fix: increase compressed UPDATE_OBJECT decompressed size limit to 5MB

Browse source 
Capital cities and large raids can produce UPDATE_OBJECT packets that
decompress to more than 1MB. The real WoW client handles up to ~10MB.
Bump the limit from 1MB to 5MB to avoid silently dropping entity
updates in densely populated areas like Dalaran or 40-man raids.
