chore: use ranges in EntityManager and touch up (#1451)

Browse Source 
* EntityManager: ranges and cleanup

Use LWOOBJID for ghosting entities
use ranges::views::values for associative container iteration
remove dead code
comment magic numbers
little bit of optimization (not enough to be game changing or take the time to measure, they are free speedups anyways, we take those)
use cstdint types

* use size_t

* use lwoobjid for ghost candidate
