WarUtils.isRelated() has inverted equality checks for version, type, classifier, scope

## Bug Description

`WarUtils.isRelated()` at `src/main/java/org/apache/maven/plugins/war/util/WarUtils.java` lines 69-80 has inverted equality checks. The method returns `false` when `version`, `type`, `classifier`, or `scope` are **equal** between the artifact and the dependency — the opposite of what's intended.

The method should return `false` only when these attributes **differ**. As written, the method only returns `true` if every one of these four attributes differs while groupId/artifactId match.

## Impact

This makes `registerTargetFileName()` in `WebappStructure` effectively broken: a dependency will never match its artifact when any of these attributes coincide, and could match the wrong dependency when they all differ.

## Code

```java
if (Objects.equals(artifact.getVersion(), dependency.getVersion())) {
return false; // BUG: should return false when NOT equal
}
if (Objects.equals(artifact.getType(), dependency.getType())) {
return false;
}
if (Objects.equals(artifact.getClassifier(), dependency.getClassifier())) {
return false;
}
if (Objects.equals(artifact.getScope(), dependency.getScope())) {
return false;
}
```

## Expected behavior

Each `if` block should use `!Objects.equals(...)` so that `false` is returned only when the values differ.

Start in src/main/java/org/apache/maven/plugins/war/util/WarUtils.java at WarUtils.isRelated(), lines 69-80, and review how registerTargetFileName() in WebappStructure depends on it. Verify that the method returns false when version, type, classifier, or scope differ, and can match when those attributes are equal.
