Mark some specific furnitures/terrains examine as always allowed in faction territory

[RenechCDDA]

Summary

Bugfixes "Mark some specific furnitures/terrains examine as always allowed in faction territory"

Purpose of change

• Closes "Stealing" checks are too aggressive #77239

Describe the solution

Add a flag FREE_TO_EXAMINE to the common furniture/terrain that should always be examinable.

If that flag is present, the locals will never care about you examining it.

Added to the following furniture/terrain:
Translocator (magiclysm)
Exodii sign at their main base and all other f_sign by extension
Exodii sign at their barns (not faction territory atm, but just in case)

Describe alternatives you've considered

Tying it to the examine actor/function

Uh it turns out that a flag was incredibly simple, so the flag was chosen instead.

Testing

Spawned a sign at a faction territory

Examined glass display case, got warned

Examined sign, no warning

Additional context

#77239 (comment) is a problem with the design. There's no way in and the prisoners SHOULD be upset about you forcing your way in (they're barricaded to keep the zombies out). I don't know what to do there 🤷

This PR was way easier than I thought.
