IGNORE_SOUND, NO_BASH and RETURN_TO_START_POS traits to more NPCs.

Is your feature request related to a problem? Please describe.

#62439 added the ability to give static NPCs mutations that stop them from investigating sounds or bashing terrain, and tell them to return to their locations when they are done other stuff.

Solution you would like.

These traits should be added to most static NPCs. For now, the ones that can be recruited don't need them, although a better way to do that would be to give them these traits and then remove them when you get to the dialogue that allows you to recruit them.

Guard NPCs should probably still investigate sounds and bash terrain.

Describe alternatives you have considered.

Improving the AI to do this on its own - most of these traits should be reworked into conditional AI features instead, after stable. However, "no investigate" should remain a common one for a lot of these NPCs.

In stable, we should probably re-evaluate NPC decisions to bash a lot more, and have them start moving furniture when they would have bashed it.

Additional context

Not every NPC needs to be covered for stable but most should be.

Do we think #62493 caught the remainder that needed this?

[I-am-Erk]

Perhaps, but #62472 still needs to be finished off.
