Normalize whitespace and line endings across Java source files

[Copilot]

Standardize line endings and whitespace formatting across the codebase to improve consistency and reduce diff noise.

Changes:

• Consolidate 3+ consecutive blank lines to single blank lines
• Strip trailing whitespace from all lines
• Remove trailing blank lines at end of files
• Ensure all files end with newlines

Scope: 18 of 27 Java files required updates; 9 were already compliant.

Example:

// Before
public class A {

    public void action() {
    }


    public void action2() {
    }

}

// After
public class A {

    public void action() {
    }

    public void action2() {
    }
}

All Java files compile successfully post-change.

Summary: This PR standardizes whitespace and line endings across the Java sources to improve consistency and reduce noisy diffs.

Changes:

• Ensures files end with a trailing newline (removes \ No newline at end of file cases)
• Removes extra blank lines within files and at EOF
• Strips stray blank lines around imports and within test helpers

Technical Notes: Functional code is unchanged; the intent is purely formatting normalization to keep future diffs clean and tooling behavior consistent.
