Ashwalker Tribe roundend reporting revamp (#75506)

## About The Pull Request

This PR changes how ashwalkers are listed in the roundend report.
Originally, they would be listed as individual "other" antagonists,
which isn't a particularly great way of handling it and leads to
weirdness like this:

_(That's an authentic ninja greentext from a live server, by the by)_

Now, the roundend report gives each ashwalker team their own section
within the report, whether or not they succeeded, and some bonus stats.

This new roundend report handling also supports having multiple
Necropolises (Necropoli?) in the same round. Each tribe has their stats
and success reported individually.

This also slightly modifies the protect_object objective, preventing
hard deletes when linked to objects that don't clear their own
references.

## Why It's Good For The Game

Gives Ashwalkers a much better roundend report, and handles how the
reporting is done in a much more sensible manner.

Reduces how much space that large nests take up with their individual
listings.
