v18.0.9: Fix claimed double chest split + admin claim chest boundary fix

GriefPrevention3D v18.0.9

Wiki: GriefPrevention3D Wiki

Thanks to @thiagorigonatti for fixing these issues!

Upstream Issue Fixes

Placing a chest next to a claimed double chest breaks the double chest (#2606)

Before: Placing a single chest outside a claim adjacent to a double chest fully inside the claim would forcibly split the double chest into two singles — even though no cross-claim double chest was actually formed.

After: The double chest is left untouched. Only adjacent single chests are candidates for the cross-claim split logic; existing double chests inside the claim is preserved.

The fix adds a guard that skips neighboring chests that are not Chest.Type.SINGLE, preventing modifications to existing valid double chests fully inside a claim.

Single chests on claim borders can be extended into double chests from outside claims (#2609)

Before: A player without build permission could place a chest outside an admin claim next to a claimed single chest, and the claimed chest would be extended into a double chest crossing the claim boundary. This happened because both wilderness and admin claims have a null owner ID, and the boundary check treated them as the same owner.

After: The chests are kept as separate single chests. A sameClaimOwner helper uses reference equality for null claims, ensuring wilderness and admin claims are only considered the "same owner" when both are literally null (both wilderness).
