Fix excess trailing newlines in Java source files

[Copilot]

A previous cleanup operation inadvertently added multiple trailing newlines to the end of Java source files. This follow-up corrects the issue by ensuring all files end with the proper format: closing brace } followed by exactly one newline character.

Changes

• Trailing newline normalization: Removed excess trailing newlines (2-4 newlines) from 4 Java files that had been affected
• Files corrected:
  • microsphere-spring-cloud-gateway-commons/src/main/java/.../config/ConfigUtils.java
  • microsphere-spring-cloud-gateway-commons/src/main/java/.../config/WebEndpointConfig.java
  • microsphere-spring-cloud-gateway-server-webflux/src/main/java/.../util/GatewayUtils.java
  • microsphere-spring-cloud-gateway-server-webflux/src/test/java/.../filter/NoOpGatewayFilter.java

Example

Before (incorrect):

    private ConfigUtils() {
    }
}
[extra blank lines here]

After (correct):

    private ConfigUtils() {
    }
}
[single newline at EOF]

All files now follow the proper format with closing braces preserved and no extraneous trailing newlines. Code compilation verified successfully.
