Chapel touchups and bugfixes (#22774)

As title. Fills in the recently remapped chapel with some extra
detailing and resolves a few bugs surrounding it. Gives the chaplain
back a few of the toys they already had, such as their crematorium, as
well as a few others.

Note the in-game screenshot is after some playtesting, so not everything
is where it should be.
