Fixes pet commands that required pointing (by fixing pointing) and fixes pets being unable to attack (#95910)

## About The Pull Request

This is a two-parter but they are part of the same journey; I was fixing
#95715 and noticed the commands didnt work, so I also fixed that #94689

The issue for #95715 was that pets did not have their damage set at all,
so they could not attack on combat mode. Dogs specifically circumvented
this by setting and reverting the damage during behavior, which is not
what ai behavior should do. Now those values are the same. I set it up
as 5 lower and upper by default on pets, but if I need to tweak that let
me know.

For #94689 the issue is that if pointed_at's loc is a turf, it would
override pointed_at to be the turf, so that it could pass the view()
check below. But by setting pointed_at everything after now uses that
for the logic, including the signals. Which means the logic often just
thought you were pointing at the floor. I've fixed this by assigning the
loc to a temp var and not changing pointed_at

## Why It's Good For The Game

Dog-mauling is back, this is a good thing.
