[Magiclysm] Wolfshead Cufflinks changes stats permanently

### Describe the bug

The activation of Wolfshead cufflinks changes the Strength stat by +2 and intelligence stat by -3 after the werewolf aura wears off.

### Steps to reproduce

1. Acquire "pair of wolfshead cufflinks"
2. wear and activate the cufflinks
3. Wait for aura to wear off
4. Note permanent change in stats

### Expected behavior

I expected the aura to only change the stats temporarily, but after waiting out the duration, some stat changes became permanent.

### Additional context

I already have a probable cause, The aura_werewolf is the only item so far that seems to give the player temporary mutations with inherent changes to stats (Apex Predator[PRED4], Large[LARGE_OK]), the mutations seem to align with the permanent stat changes and I assume it doesn't return the stats when the mutations are removed.

If I'm correct than I'm not real certain of a good fix besides removing those mutations from what is given.

Start by reproducing the issue with the Wolfshead cufflinks, then trace the aura_werewolf effect and the temporary mutation removal path, especially mutations with inherent stat changes such as Apex Predator and Large. Done means Strength and intelligence return to their pre-activation values after the aura wears off, with regression coverage if the existing test structure supports it.
