Bugfix: IK-30 spread issues and dev configuration assertion crashes

About the PR

Fixed the IK-30 spread bug when the weapon is wielded

Technical details

It inherits from BaseGunWieldable, which by default has a GunWieldBonusComponent

  - type: GunWieldBonus
    minAngle: -20
    maxAngle: -30

The issue is that SharedWieldableSystem literally adds these values onto the base values:

private void OnGunRefreshModifiers(Entity<GunWieldBonusComponent> bonus, ref GunRefreshModifiersEvent args)
{
    if (TryComp(bonus, out WieldableComponent? wield) &&
        wield.Wielded)
    {
        args.MinAngle += bonus.Comp.MinAngle;
        args.MaxAngle += bonus.Comp.MaxAngle;
        args.AngleDecay += bonus.Comp.AngleDecay;
        args.AngleIncrease += bonus.Comp.AngleIncrease;
    }
}

The IK-30 (and the IK-60 inheriting from it) had a base minAngle of 1 and maxAngle of 4, causing these values to be negative, with maxAngle being smaller than minAngle.

I fixed it by simply adding a GunWieldBonus with 0-0 angles to the IK-30. The other alternative is to rework BaseGunWieldable but it's upstream territory.

A test should probably be written to scan for occurrences of this bug, since it's really easy to accidentally run into. But that should probably be done upstream.

Requirements

• I have tested all added content and changes.
• I have added media to this PR or it does not require an ingame showcase.
